In my "career" of chess, I still learn things after 12 years. This year my focus is to not downtalk myself before a game against a strong opponent. It is part of my personality to do that. I also do that in more common situations. Chess just provides a way to battle your own shortcomings and improve yourself.

Other things I learn by playing chess... Always play till the end, untill there are no more chances. Only then give up. I learned to lose better, and am still learning that. The less I am afraid of losing, the more freeflowing my gameplay is. I learned to find my way better in chaotic situations and I actually love them. I like to find the moves and game-style that gives a bit of bewonderment and inspiration.

And yes, you can learn something everywhere. You just have to pick your battles and where to fight/play them. Chess fits my personality, it does a lot to me.
