accept the fact that none of us are perfect

I disagree. Pressure makes diamonds.

Tiger moms make overachieving Asian kids who dominate test scores, overpopulate the best universities, create successful businesses or go into high-paying professions. There is always constant pressure to be perfect, to do better. Nothing is good enough.

It may create some mental problems later on, but you can't deny the fact that they are "successful" by modern definitions of the term.
