MIstakes

I believe human make mistakes. People always say mistakes are the process of learning. However, when mistake are repeated again and again. This is unforgivable. I don't know why I keep on repeating the mistakes for so many times. I put in effort and I tried to change. Though, I can't see any improvement on myself. Can some1 tell me what am I supposed to do at this stage. I really feel like giving up.......... Maybe I just don't suit to be in that game.....

I really feel so sorry for those who put in effort to teach me and I think they have given up as well...
