Mike Tyson is one of the greatest boxers of all time and also a big fan of MMA. He has shared some great advice for Mixed Martial Arts fighters and human beings in general:
Came. Saw. Conquered. Got conquered. Bounced back.
I refuse to let adversity allow me to be average.
Happiness is fleeting, just like sadness. It's all fleeting. But we have to remember in that state of happiness or sadness that it's fleeting, because if we don't we can make bad decisions during that time.
