No everyone doesn't. Some people are born sick, some have better cardio, some take more weight easily, some people are born twice as big, some grow very little...

And it's the same with mind abilities. Your mind have various qualities, and you are not born equals to others. Some can concentrate better, some can abstract less, some more creative, some are shy.

Add all the differences, and yes, you have people that will have an easier time than others. Bolt and Tyson have been trained, but they started with a nice base to work on.

OK, I didn't consider health issues.

And obviously some people have easier or harder times. I am simply more aligned with modern humanist psychology, believing environment is way more relevant than genetics.

This doesn't mean you're at fault for sometimes having a hard time keeping up, this just means that it's most likely not in your genes.
