No, that's actually the science. You are what you are born. You can hone what you are born with, but if you are born with a shitty voice, you will never be Elvis Presley, and if you born a dwarf, you will never play for the NBA, and if you are born with average intelligence, you will never be an Einstein.

The fact that you buy into all this self-improvement shows that you have not yet arrived at that point where you realize it's a load of bs. I studied this 30 years ago. It doesn't work.
