One thing no one will ever take away from me is my happiness.

A positive attitude with some direction can get you far.

Sometimes I get down and knocked out, no one goes undefeated. But I pick myself up, and keep going. Cause I am tough.

Responsibility: Be responsible, sure you can drink, but don't drive. If you’re going to have sex, use a condom. Common sense.

Courage: In order to get ahead in life you need to be a go-getter. Things don't just come to you.

If something makes you unhappy, brake away from it, cause it'll serve like a virus and just spread across your mind and not only effect you mentally, but eventually unhappy feelings and thoughts get to you physically.
For e.g.: crying and sleeping behaviors (too much, or not enough) etc.

Be courageous, do what's right for you, don't let some sucker live your life for you. Go out there, and just have fun.
