The best advice I've got was - "All you have is the process. All you have is the journey of making something. Once you're done you have absolutely no control on how it's received, or if people like it or hate it, or what is done with it. As long as you enjoy the process, then you'll always be happy." I really feel like that's important advice. Sometimes we get so focused on the results that we miss doing it - we miss the adventure of being in the midst of something because we're looking too far ahead.
