Think about what you can do in life. Think about how you can achieve that. Think about what would happen if you don't try in school. Think... If you don't try in school, then your future will crumble. It will crumble like a Jenga tower, however, you wouldn't know when your life crumbles too. Think BIG, and succeed.
Never Give Up
Life may be a struggle, you may feel down sometimes, or you might feel depressed. You might want to give up, however, just reach for the limits, and think. Think about your life. How great your life is. Thing BIG. Think positive, just never, think about giving up.
