The person who is hated the most has the best genetics. This is because they are successful and captialize on their good genetics by also working hard. This makes people who don’t work hard feel inferior so thus, they blame everything but themselves for their lack of success.
Simply put, if you are successful you have good genetics. Just some people’s genetics are more mental than physical.
If someone “could’ve gone pro but the coach hated me” then he has shitty genetics because he is too stupid to do what is necessary to play the game. Thus his mental genetics/will to succeed is weak. And let’s be honest, if a coach HATED Michael Jordan he’d probably still play him. Because he is good.
