Fear is one of the most powerful emotions that paralyze human potential. If you feel fear, listen to it, take precaution, prepare to increase your confidence, but never ever let it stop you from anything. A weapon against fear is vulnerability. If you accept and admit your fear, than you are not ignorant to it anymore and you can tackle it and take action. This is why I think fear is the easiest feeling to master. Once you eliminate your ego which is trying to escape it, or attach yourself to it, and you use it to your advantage, than you realize what it is trying to tell you, and you can take action.
