I believe that people are scared of achieving greatness. Without giving it a second thought, the idea of being great seems as if it would come with a lot of work and huge responsibility. By now it's no secret that the things that have brought us the most pleasure in life are those that we've given more time to and put more work into. Even if you misfire and don't hit the greatest day of your life you could end up short at an awesome day. This will take much effort on your part.
