Know that being street smart is just as important as being book smart.
While school is important, being book smart is not the only thing that you will need to excel in this world. Book smarts help you understand what you are talking about and will give you an idea on which path to choose, however street smarts allow you to use your intuition to analyze any situation at hand.
Your street smarts will allow you to see things that were never really presented in those books you read. A perfect balance between street smarts and book smarts will prove to be a handy tool in your future endeavors.
