What are the best non-financial goals to aim for which can give you greater control of your life?

Mastering your mind. While all of your goals are personal to you, I think the number one goal that can give you greater control of your life, no matter who you are or what situation you are in, is to have control over your own mind. Everything you feel, do, etc. stems from your thoughts. If you can control your thoughts, you can literally control your emotions (imagine being that overly joyous, happy go lucky person every minute of every day?) control you habits and behaviors (imagine always being on point and productive?) and therefore have control over your own reality.
