Again, the quote is literally just saying don't quit just because you don't see immediate results. It's not saying some people don't have a leg up over others and that everyone is created equally.

I'm actually impressed you managed to take "don't give up on a goal if it seems like you're you're not progressing as fast as you would like" and twisted it into "anybody can beat Michael Phelps if you work hard enough" what type of sad, failure of an individual does such a thing lmaoooo
