Our minds are the most powerful tool we own. Each thought you create becomes your reality. If you think it, or better yet, say it out loud: "My height, skin color, cultural heritage, sexual orientation, and gender are all perfect", this will become your reality. Your subconscious mind will accept that as truth, and your self-esteem will inflate. Within a short time, your confidence will develop to the point that you will realize the power of your concentration. In time, you will attract like-minded people, and anything is possible.
We gain strength, courage, and confidence through each experience in which we stop to look fear in the face. We must do that which we think we cannot.
