Affirmations are a powerful tool to reprogram the subconscious. Affirmations are said in front of the mirror in the morning immediately when you get up and in the evening right before you go to sleep. Affirmations generally get a bad rap. It's easy to dismiss affirmations as hokey, and, in a way, they are. But affirmations are also incredibly empowering.
Affirmations illustrate just how powerful language can be.
I challenge you to use affirmations for a week and see if they make a difference in your underlying attitude. Another method to improve self-confidence is through visualization. High-performance athletes visualize winning a race before running it. During the actual race, they merely put into action what they have already visualized. You can use visualization to be successful in law school before you crack a book.
