I wanna quit

I'm thinking about quitting cotw because I feel I am bad at the game, first I messed up the albino diamond bear on medved and now my friend got his first diamond when I haven't gotten one in about two years of playing and he started this year, the albino roe deer I have was from when I went to do something and my friend shot it and saved it on my account, and he's gotten an albino croc. Should I quit??
