Fear is an emotion that has the potential to stop you in your tracks. While listening to, and following, your heart and gut is very important, fear is a totally different beast.
Most things people fear, never happen. Courage is not the opposite of fear, it is acting in the face of fear. Do not let fear stop you from pursuing your dreams, love, adventure or anything else.
Fear of failing is a fear that cripples. So what? We all fail from time to time. Some more than others. Edison failed over 10,000 times before he produced a functioning filament. If he had quit after even 9,999 times, he would have failed completely.
So act in the face of fear. "You gain strength, courage, and confidence by every experience in which you really stop to look fear in the face. You are able to say to yourself, 'I lived through this horror. I can take the next thing that comes along.'" Eleanor Roosevelt
Fantasizing the freedom to look fear in the eye and push ahead.
