Action is the cure for fear, and hesitation and procrastination will continue to nourish fear. It means that people will laugh whether we do it or not. If we can't do it well and people will laugh, then let's do it well and give people a laugh! The world is not in the hands of those mockers, but in the hands of those who can stand ridicule and criticism and keep moving forward.
This is a famous saying of lev tolstoy.
