Be happy. Be kind. Be brave. Don't be afraid; think instead of all those times your fear was unwarrented. And don't be afraid to fall in love. It's called falling for a reason.
Believe in something, no mater what it is. Believe it truly, deeply, with all your heart. Have something in your life worth dying for. Have something in your life worth living for. And fight for something every now and then.
Do what's right for no other reason for that it's right. Know who you are, but don't be afraid to change it. And know that no matter who you are, you are IMPORTANT. You are part of something BEAUTIFUL.
