It is of utmost importance that you make it your goal to constantly, consistently feed your mind. The only difference between someone who is successful and someone who is not is the way each of them thinks. If you are to fulfill your goals and dreams, you must be strengthening your mind. You must focus on keeping your mind in top condition.
