Live a life with trouble. Experience chances you are given whilst your still young because one day you will look at the world and regret the things you didn't do. It's best to do it whilst you can because the future can change in ways nobody can predict and life can be difficult and it always will be but that isn't an excuse to give up hope. 

Be you and do not let anybody say you aren't good enough because as long as you try your best. Your life will change in ways you will never see in anyone.
