If you can be at peace wearing a funny costume or drawing caricatures or simply being present in the moment to make someone else's life a little better, then someone else's definition of success holds no weight.
You want to get the gig? You want to make the deal? You want to grow the sales? You want you want you want? How bad do you want it? Show me any "overnight success" and I'll show you the "dog years" of "overnight." Marathon, not sprint.
