What are some uplifting quotes for teenagers? uplifting but NOT corny?

so i read this thing in glamour where people write down inspiring quotes and post them on walls or signs or wherever people will see them. i figured that would be an awesome way to spread positive energy and make someones day a little better. and if it doesnt do that, it might be fun anyway. so i need really good quotes for these. not your typical inspirational quotes. i need ones that will stand out and actually affect people! thanks so much!
