There doesn't seem to be a more worthwhile endeavor to dedicate your life to than to see what you are capable of. - Dan Koe

If you haven't developed yourself in any capacity, your current purpose, and the ones following, will increase in meaning as you solve your own problems. Start with what's right in front of you. Are you overweight and sluggish? Do you hate your job? Are you dealing with relationship issues? Is your mind a storm of negative thoughts and emotions? You must confront what's causing the most pain in your life, dance with that pain, and create a plan to solve the problem. When you solve that problem, not only will you build momentum into the next, but your other problems will become easier to solve. This is not a linear process. Your problems are a tight-knit web that bind you to your current situation. Problems don't exist on their own.

It’s crazy how you can just learn anything you want and become so good people can’t ignore you if you stop getting distracted.

The primary reason people don't achieve big goals is because they don't realize that the only source of truth is making mistakes. They soak up advice and theory, expecting it to be an exact match to their mind, experience, and situation just to fail once and give up completely.
