I was probably more scared of my high school exams than I was of the Oscars. At the time you think it's everything and if you don't do well your life's over. Opportunities are gone. So the more you do it the less the fear is present.
The marvelous richness of human experience would lose something of rewarding joy if there were no limitations to overcome. The hilltop hour would not be half so wonderful if there were no dark valleys to traverse.
