Don't stumble on your failures and think more about your successes, keep on going on. That's the only way to success or live in general. We all know how hard sometimes it gets, it's terrible, but we can't let it be it for us. It's not how we succeed in life that defines us rather than how much do we try to succeed. And not giving up is the key to that. Not giving up is the only way how one day it could get better, so hang on!
