You always have a place to come home to. Make new friends. Don't forget the old ones, but make new ones. They can be just as cool. If you're going to college, don't worry if you're always broke.
All college kids are broke.
Don't worry if you're unsure about what you want to do. Waiting is better than jumping into something you really don't want to do. Sit back and it will come to you at the right time. Always have respect for others. The only way to make it in the world is to give.
