Time to change!!

I always had a life with no regrets. Whatever i did I always had a reason to convince myself that it was not wrong, but things have made me rethink now. I regret lots of things. Need not mention everything, but as Khalid says " It's never a wrong time to do a right thing". I think I need to change, I'm working on it.

I promised something last night and broke it in the morning itself. I just need to figure out myself.
Is it better
a) to change and be a different person
b) to remain the same and continue with the comments that end up hurting people?
