When you start off, you have to deal with the problems of failure. You need to be thick skinned, to learn that not every project will survive. A freelance life, a life in the arts, is sometimes like putting messages in bottles, on a desert island, and hoping that someone will find one of your bottles and open it and read it, and put something in a bottle that will wash its way back to you: appreciation, or a commission, or money, or love. And you have to accept that you may put out a hundred things for every bottle that winds up coming back.
