thankz sir for your question. there is no such decission that i would like to change ,i think good as well as bad experiences are equally needed for a person to groom himself and what i am right now is due to those decissions i made in past and i am satisfied with myself. 

Well ! we Can't change the past.But that experience teaches us to do better every time.
So what ever the work i do i will be very cautious before doing it.
