You can't let your failures define you, you have to let your failures teach you, you have to let them show you, what to do differently the next time. So if you get into trouble that doesn't mean you're a trouble maker, it means you need to try harder to act right, if you get a bad grade that doesn't mean you're stupid it just means you need to spend more time studying "no one's born being good at all things" you become good at things through hard work.
