WISDOM BITS - emotions can always be either your downfall or your upliftment. In sports for example.

"Your mind is like mold waiting to be shaped. You can turn it into a temple, a garden, a lush forest, or a circus or worse, psychiatry or even hell. Choice is yours. To a sick society it's always better to externalise power by reacting emotionally to everything, so you stay overactive, fail partly in everything, grow in frustration so that you eventually crumble. And then you end up in other people's hands... And we all know how things can go..." - Miyumi Kurokami
