Self Problem

Every people do wrong things in the life, there is no matter how serious of small problem we had created to others... the important thing is, do we really learn from the mistake that we had done, and improve it? there is no point to blame others and fine so much excuses to change the topic... meaningless... Some time, when i really put down my self and try to recall back what had i done to the people around me, i feel guilty and useless, because i had never really put down my self to learn from my mistake, at last i had hurted others and for sure Myself.. T.T...... Try to recall back what had done by us to others? no excuses finding, solve the problem. It's not hard to say a sorry to those people that we had hurted them badly. You will found it this world is still peacefully and friendly~
