That's the cruel joke of making, or any creative discipline for that matter: no matter how much you progress in your career, the duality of thrill and terror that exists with all new things will never leave you. In fact, the better you get and the more experience you acquire, the better you are at understanding objectively where your work and your wisdom fall short. Self-doubt never leaves the attentive craftsperson, so you best make friends with it. And if you don't know how, here's some advice: have the patience and humility to ask someone who's been there before.
Adam Savage, in “Every Tool’s a Hammer”
