Willpower is a muscle

Reading about willpower made me realize some things about myself. Willpower is a muscle and can be improved. I realized I have been doing this all my life.

I'm particularly good with sports.
When doing sports, after reaching the self proposed goal, I did this to prove myself I could go beyond the goal:

cycling
- just one more block
- just more 5 minutes
-  now do it again but using another way

Weightlifting
- just more 10 reps
- after the extra reps, more extra reps
- slap in the face and self cursing/motivation

Soccer (PE class)
- no matter how tired, no matter how slow I might have become, always fight back and try to have the ball and reconstruct the game.

Endurance Running (PE Class)
- no matter how tired, no matter how slow I might have become, always fight back, my friends give up very soon and I don't want to be like them, I need to show my teacher I am resistant and can take this.

Endurance (and Velocity) Running

- I like doing both during Summer and actually my trick was, before breaking the endurance running (taking a break), I would make the transition into speed running to completely deplete myself and prove that even though I was tired from the endurance training I could still use my velocity in case of emergency. But be careful not to pass out. The last time I did it, when I stopped I was starting to black out soon after I sat and started resting. Nothing happened.
I sometimes imagine myself running away from criminals trying to assault me lol. The next time I do it I will imagine myself running away from zombies. "Run for your life!"

What I love about endurance sports is that there's always ways of improvement. There's no limits, the only limit is oneself. You either continue practicing, getting better and forging yourself or you give up.

Language learning
- Just one more word.
- Just one more sentence
- just one more grammatical point
