One of the most important things for you to discover is the basis of your fear. When you understand why something exist, it is easier to pursue a solution. One of the major contributors of fear is a lack of self-confidence. Another is the fear of rejection. It is never more important what others think about you, as it is what you think about yourself.
If you constantly live in fear, you will never know the joy of your potential. My dad use to tell me, "the only thing that beats a failure, is to try. Stop being afraid of what might happen and experience how your fear diminishes when you do. There is no one like you in the whole universe, you are special, embrace your uniqueness and experience life!
