Enjoy the power and beauty of your youth. Dont complain about your body right now because in forty years you'll want it back. Enjoy the smoothness of... your wrinkle-free face, for it won't stay that way for long. You can only be young once so don't waste it trying to act older and more mature.
Dont worry about the future. Dont regret your past. Life is to live it at the moment because, why regret something that already happened or worry about something that may or may not happen? You need to enjoy today because you dont know if you're going to have a tomorrow.
Do one thing everyday that makes you laugh.
Dont take other people's heart for granted. Dont let anyone take your heart for granted.
Dont waste time on jealousy. Jealousy is an endless vicious cycle. Someone will always have something you want and you will always have something someone wants.
Remember all the good memories. Ignore the pain. Once you learn to forgive, you'll be able to forget.
Keep all the meaningful things. Throw away whatever made your heart ache.
Dont feel guilty if you can't make everyone happy. The only person you should make happy is yourself. Dont let anyone dictate your life; make it as you want it to be.
Take care of yourself. Don't harm your body in any way; physically or mentally.
Maybe you'll marry, maybe you won't. Maybe you'll succeed, maybe you won't. Maybe you'll live your life depressed, maybe you won't. Everything depends in what you want.
Don't be too conceited; you're not better than anyone else. Don't be too modest; no one else is better than you.
Enjoy your body. Don't be afraid of what people might think of you. Your flaws are what make you beautiful.
Sing, even if you're really out of tune.
Listen to people, even if you can't relate because, someday, you'll want to be heard too.
Get to know your parents because, someday when they're gone, you'll wonder who they were.
Be nice to your siblings. When your parents are not there anymore, they're the only family you'll have left.
People come and go in your life, but only a few leave footprints behind. Keep those people close because, as you get older, you begin to realize that it is more important to have REAL friends than a lot of friends.
Love someone, but don't fall for them too hard.
Love someone, but don't let love make you soft.
Accept certain inalienable truths: people will break your heart, but you'll be able to mend it. You'll fail, but you'll succeed. You'll make mistakes and regret things. But, at the end, you'll realize everything happened for a reason.
Experience new things.
Never count on people because someone someday will disappoint you and, when they do, you won't trust anyone else. Someday you'll find someone you can really count on, but you should still have a mind of your own.
Be careful whose advice you buy, but listen to those who give it. Advice is what makes you think twice about doing things you're not sure about. But, always follow your heart because it will always be right. Keep the advice, though, and share it with others, that way it'll be worth more.
But trust me on smiling.
