nothing, 'coz if i would regret something that would mean i would not respect my choices i've made and if i would not respect my choices i would not respect myself 'coz all my choices in life have get me to the point where i am now in life, so there is nothing to regret.
Мое мнение о природе человека
The human nature is all kind of things, curious, peacefull, loving, and so on. It can not be said that something is good or bad, people are who they are and they are to experience and expressing themselves in the best way they possibly can.
