Some advice...

Don't waste your time on jealousy, sometimes your ahead, sometimes your behind, the race is long, and in the end, it's only with yourself. Do one thing everyday that scares you. Don't be reckless with other peoples hearts. Don't put up with people who are reckless with yours. Enjoy your body, use it every way you can, don't be afraid of it, or what other people think of it, it's the greatest instrument you'll ever own, and you only get one chance with it. Don't read beauty magazines, they will only make you feel ugly. Get to know your parents, you never know when they'll be gone for good. Be nice to your siblings, they are the best link to your past and the people most likely to stick with you in the future.
