How many times have emotions like fear held you back from doing something you really wanted to do? Going somewhere you really wanted to go? Being with someone you really wanted to be with?
Fear can be the big dream buster. Our unconscious mind sometimes stops us from reaching our full potential...but only if we let it. It tries to protect us and keep things comfortable. As humans though it is our natural path to grow, to keep learning, to keep evolving. Without new experiences we will always in some ways be unfulfilled.
