Not a big fan of Will Smith but these words have never been truer. God has placed the best things in life on the other side of your fear. In your comfort zone you will never grow.
I agree with him.... to a point. Sometimes on the other side of your fear is when the worst you ever dreamed of comes true. How you handle that worst case scenario is what separates the men from the boys. Go there often enough and pretty soon you become comfortable with the sensation.....
