am i do the right thing?

I had been thinking a lot lately. all along what i have fight for my right,is it wrong? i am admit that i don't think wisely and act smartly but... i don't know..

I am confused.. I just want make an hypothesis here.. let just say, my exam grade not good, all for what happen is all my fault.. I know I shouldn't blame my self but if that can make me feel better..so be it..

I also know that we should never regret what we have done in the past and work better for our future. Don't hold the past but we cannot run from the past,right?
