Why Is It Important to Define Your Purpose in Life?

Tags: , , Posted byJD Moyer on

Got Purpose

It sounds intimidating, to define purpose in your life. It also sounds unnecessary. Why not just live? Why not just enjoy life, and take each day as it comes?

I don’t think there is any ultimate purpose in life beyond what we decide is important. I think James Altucher puts it well in this post:

“People get depressed now if they feel they are not fulfilling a purpose in life.

Here’s what I think purpose is: the universe doesn’t know anything. So it cut off tiny pieces of itself to go out there and experience things, any things, and then come back home when they were done.

That’s it. So whatever you are experiencing today, good or bad, the universe is learning and happy and grateful to you because it is exploring new things about life.

BAM!

No other purpose.”

I don’t believe in any kind of singular, universal purpose (not even the poetic purpose Altucher describes), but I do feel better and live better when I live by my own principles. What do I think is important? How much am I willing to bet on those values? How ’bout everything. All in.

Neil deGrasse Tyson, in a beautiful response to a question on a reddit, “What can you tell a young man looking for motivation in life itself?” gets to the core rationale for defining one’s own purpose in life:

“The problem, often not discovered until late in life, is that when you look for things in life like love, meaning, motivation, it implies they are sitting behind a tree or under a rock. The most successful people in life recognize, that in life they create their own love, they manufacture their own meaning, they generate their own motivation. For me, I am driven by two main philosophies, know more today about the world than I knew yesterday. And lessen the suffering of others. You’d be surprised how far that gets you.”

Love, meaning, and motivation all work together. You can discover what gives life meaning for you by listening to your heart, in fact I think this is the best way to discover meaning. For Tyson, increasing personal knowledge and reducing human (and perhaps also animal) suffering reflect his core values (codified into purpose, or “main philosophies” as he puts it). He advises the young man looking for motivation to decide what is important to him, and then act on it.

If the word “purpose” rubs you the wrong way, consider defining your “core values” or “life philosophy” instead. For you, what gives life meaning?

A purpose in life: motivation and goals

Does motivation automatically flow from purpose and meaning? Not necessarily. Low motivation can be a sign of low dopamine in certain parts of the brain, depression, and/or overstimulation.

But jacking up the neurotransmitters involved in motivation doesn’t actually lead to productive or helpful activity unless there are already well-established habits in those areas (yes, the movie Limitless is a fantasy). For example, bromocriptine is a powerful dopamine agonist. Side effects include gambling and compulsive shopping. Reward-seeking behavior, in other words, but not really what most people think of when they think about motivation. Drugs like modafinil can enhance concentration, motivation, and cognitive abilities, but come with disruptive and potentially health-damaging side effects. Video games are designed to jack up reward-seeking behavior, and sometimes the dopamine boost can overflow into other life areas. But just as easily, video games can suck time and energy, providing the feelings of motivation and drive (achievements! points! levels!) without any real-world effects.

Goal-setting can also temporarily increase motivation, but if a goal isn’t purpose-driven, the motivation boost will be short-lived. If I don’t care about money very much, setting a “goal” to become a billionaire isn’t going to do squat. Even if I come up with a plan and work that plan like a maniac, I’m going to lose steam if I don’t actually care about becoming rich. Goals shouldn’t require motivation, they should provide motivation. And goals only provide motivation when they line up with life purpose/core values.

Here’s my own system for turning purpose into action. Feel free to steal it (I’ve stolen all the bits from other people).

1. Make a 5-year commitment that is true to your life purpose (and/or values and/or life philosophy). Where do you want to be in 5 years? As Steve Pavlina points out, we often overestimate what we can do in a single year, but underestimate what we can do in five years.

2. Choose a single actionable goal that supports your 5-year commitment. Give yourself a target date. If it appeals to you, set up additional rewards (completing the goal will be a reward in itself) and “kick-in-the-butt motivators” (I prefer this phrasing to “punishment”) around the goal. For example when I was trying to finish the first draft of my most recent novel, I promised myself I wouldn’t consume any alcohol until I finished (which resulted in this post, and also finishing my first draft).

3. Commit to a daily practice (don’t break the chain!) that moves you closer to your goal. If you can, complete this practice early in the day, when your willpower and concentration are at their highest. If you don’t have that luxury, just carve out some time every day. Even an hour a day of focused work will get you somewhere.

Even if you don’t choose this kind of structured approach to living your life, it’s still worth it to choose your own purpose in life. At the very least, you’ll have something to fall back on when the “What am I doing here?” question pops into your head. And oh yeah, you’ll live longer.

Why Walnuts May Help You Stay Lean

Why Walnuts May Help You Stay Lean

Walnuts are a dietary paradox – or at least they appear that way. As you probably know, walnuts are very calorically dense, mainly because of their fat content. Just one ounce of walnuts – that is about 12-14 halves – contains 185 calories. If you’ve ever tracked your food intake, you know that sort of thing can add up very quickly, especially if you’re just grabbing handfuls and not measuring.

But if we take a look at the literature, we plainly see that people who eat nuts are actually less likely to gain weight, and long term consumption of nuts is associated with reduced risk of obesity.

So why are nuts such an outlier?

Some have pointed to inefficient energy absorption. But other studies of nuts suggest another mechanism may be at play. Research suggests that when people eat nuts, they wind up compensating for most of the calories by eating less of other foods – without even trying.

Researchers affiliated with Beth Israel Deaconess Medical Center decided to look inside the brain to figure out what exactly was going on here. They compared people who ate a walnut-based smoothie to counterparts consuming a placebo smoothie, and the results are revealing. Check out the blog to find out what they discovered!

Exercise and Cognitive Function: Get Smarter Right Now?

Exercise and Cognitive Function: Get Smarter Right Now?

It was traditionally thought that total brain blood flow was not changed during physical activity. Research in the last 10 years, however, changed this perspective. We now understand that the increased neuronal and metabolic activity of the brain during exercise drive increases in blood flow to it. We have also learned that exercise that is too intense will reduce blood flow and oxygen delivery causing fatigue. So, what is the ideal intensity to stimulate blood flow to the brain, and perhaps, augment your mental abilities in the moment?

Can Dark Chocolate Help You Get Fit?

Can Dark Chocolate Help You Get Fit?

When we think of foods that improve athletic performance, chocolate is maybe not one of the first options that comes to mind.

We’ve known for a while that certain molecules found in chocolate, known as flavonols, are associated with health benefits to the heart and the brain. Epicatechin, in particular, has exhibited widespread effects throughout the body.

But some emerging evidence suggests that chocolate may also aid in exercise performance – weird as it may sound.

Here’s what the research says so far, and how it seems to work.

What Is the Best Time to Eat? Diet and Circadian Rhythms

What Is the Best Time to Eat? Diet and Circadian Rhythms

Around this time of year, much of the world is advancing their clocks by one hour to make efficient use of seasonal daylight. Americans switched to Daylight Savings Time last week, and this week Europeans will revert to Summer Time.

When this happens, we all “lose” an hour of sleep, because we have to get up and get things done an hour earlier than we have been. This is in relation not just to the light and dark cycles of the day, but also to our body clocks.

One hour sounds like a small change, but it can make a big difference in how we function, at least in the short term. For example, data from the past two decades shows that there is a statistically significant spike in the number of car wrecks on the Monday immediately following the shift to Daylight Savings Time in the US.

As we all adjust to the time change, it’s worthwhile to consider how other aspects of our lives can sway our circadian rhythms. Circadian clocks govern the rhythms of sleep and activity in virtually all animals and are responsive to a variety of stimuli like light and stress. Research is starting to suggest that our eating patterns – specifically when we eat – can also have a pervasive impact.

Sleep Is Critical for Learning. Podcast with Professor Marcos Frank

Sleep Is Critical for Learning. Podcast with Professor Marcos Frank

We do not enter into the world with infinite knowledge of ourselves and our surroundings. We don’t have knowledge or skill to survive, to dance, or to do martial arts with grace and efficiency. We don’t know enough about ourselves or know how to interact best with different types of people we encounter. We don’t know how to accelerate our ability to get better at something. We are born, however, with the capacity to learn and to remember, and by virtue of this skill, we have an incredible potential to do great things.

Professor Marcos FrankToday, important stuff happened to you. Tonight, when you sleep, your brain will extend the process of turning that stimulation – the sites, sounds, thoughts, emotions, facts, etc. – into memories that you can access at a moments notice in the future. It’s amazing when you think about it: experiences, facts, skills, and even thought patterns become a part of who we are. How much do you know now that you didn’t know 1o to 15 years ago, or even last week, last month, or yesterday? The process of accumulating information, and accessing when needed, is so routine it’s easy to forget that something is going to make it possible. As it turns out, sleep plays a vital role in the formation of certain types of memories. In this interview, I speak with someone who has made, and continues to make, significant contributions to help the world better understand how all this magic works. My guest is Marcos Frank, Ph.D., who is the Interim Chair of the Department of Biomedical Sciences in the Elson S. Floyd College of Medicine at Washington State University. I hope you enjoy this discussion as much as I did.
