"Being happy doesn't mean that everything is perfect, it means that you've decided to look beyond the imperfections."
I LOVE this quote simply because that is what being happy is all about. If you focus on all of the flaws in life and tell yourself you can't get through anything, you won't. If you pay more attention to the good things in life rather than picking out all of the things you don't like you'll be so much more satisfied with the life you live. Life isn't going to be perfect for anyone, but its the happiest people that decide to find other things in life that make them happy rather than dwell on past experiences or focus on things that bother them. If something bothers you don't try to spend all your time fixing it, move onto something else that's worth your time.
