I recommend this whole post for people starting out in a creative venture or pursuing a lifelong passion as a vocation or for profit:
Be humble, but always try to exceed expectations. When you accept an invitation to do a talk, or do a work for a commission, do something that’s a stretch, and then do it so well that it looks like it was easy. This can mean doing way more work in a small amount of time than people think should be possible, or learning a whole new technology to do a crazy idea.
