When you start out, you don’t know a lot. Nobody does. But you gotta start somewhere.
And in fact, once a little, you’re likely to feel even more self-conscious than you did before. Because now you see the whole frontier in front of you, and you see how far you have to go. When a lot, it doesn’t matter if it’s music theory or mixing, you realize you’ve only begun to scratch the surface.
I think the people you gotta watch out for are the ones who don’t feel like imposters.
