"Character is higher than intellect." 

-Ralph Waldo Emerson 

You can be the most talented and smartest person in the world but thats not going to define you. What is going to define you is your character, actions and attitudes. These things make up who you are and they can bring repercussions, these things can ruin your future. Its better to think about your actions before actually doing them. Make sure you make the right decision when thinking about your actions. If you know its wrong, dont do it. Your bad character can get you fired, suspended from school and maybe even in jail depending on the situation. Many people dont care if you have straight As, they care about your character.
