Write down your goals, map out a plan and check to make sure, that you are doing what you need to do to get there. Also get around people who are going to help you and inspire you to be the best. This one thing can do wonder for you. Its all about staying focus, because most of us are easily distracted by outside forces, so we need to create or get in a environment that will help us.
