I’ve been told I suck at losing. Not that I’m a bad loser, I’ve learned to be far more gracious in defeat over the years, but that I am naturally competitive and goal driven. I do not like sitting and doing nothing. My brain gets bored. I need a long term goal for something I care about in order to not fall into a bad slump of procrastination and time wasting. Right now that is cycling and playing the Pokemon TCG. They seem to complement each other well. Training for bike tours keeps my body happy, and playing a very competitive card game keeps my brain happy.
The lesson here seems to be that hobbies matter, especially ones that keep you away from bad habits and too much screen time, and allow you keep leveling up and striving for new achievements that actually matter.
