Past is past already..you can never change it unless time will come back again but we all know it is very impossible to happen. So the best thing to do is to make it correct if you're doing bad from your past and make the best of your life in the future without mess..being careful and sensitive enough with the surroundings so that everything will be okay. I would say i've done so many mistakes before and I can't change that, instead focus and learn to be good in the future..though I mess up sometimes but there's one thing nice about it..it is just that I learned from my mistakes. I will never know what I am doing if I don't encounter fault. It is just a part of my lives. So I must learn to move on and continue what I've been doing despite failures and circumstances...I would say, LIFE MUST GO ON.
