If you want to build a ship, don't drum up the men to gather wood, divide the work and give orders. Instead, teach them to yearn for the vast and endless sea.
– Antoine de Saint Exupéry
Success comes from the work and ability you put in becoming better than the others, and not from some brilliance you feel you may have within you.
So don't believe that the brilliance of your idea is what will make you successful. What will make you successful is when you are out there every day, doing something new, challenging yourself, trying new methods, studying new ways, having a lot of small failures, then getting better every day.
