Who do you live for?
When you wake up in the morning, who do you think of?
When you brush your teeth, who do you not want to have bad breath for? Or who do you want to see those pearly white teeth of yours?
When you eat, why are you eating? To satisfy hunger? To gain a little weight?
When you try to lose weight, who are you losing it for? For that guy/girl you're crushing on?
When you get dressed, who are you dressing for? Your friends? People who will see you on the street?
Who are you living for?
I'll tell you what the answer should be: You. You should be the answer. You should be living for no one but yourself. When, not if, I get dressed in the morning, I am dressing for me. When I brush my teeth, I want to have minty breath for myself. I need to do eevrything for myself. You are the most important person in your life. The one person you can count on. You can't count on your mom or your brother or your friends. Correction: sure you can count on those people, but you can never be 100% sure that what you want to happen will happen in their hands. In your own, yes you can. More than 100% sure.
Live for yourself.
Be yourself. Yuo be you, and I'll be me. :)
