To nourish your mind, you must feed it with positive reinforcement daily by overcoming negativity. One way is to read positive quotes and statements from successful individuals to help reinforce positive messages and overpower negative comments. You can find quotes online or post them in places you frequent daily to read whenever you have time, such as at the doctor's office or while waiting, spending at least 30 minutes reading positive stories, articles, and books each day to continuously strengthen your mind.
