Do you experience “imposter syndrome” as a developer (Using the term lightly)? When is it okay to call yourself a “developer”?

Question

It’s hard to distinguish the line between “aspiring developer” and “developer” since learning *everything* is impossible. When do/did you first consider yourself a “developer”? Is it when you acquire a real job in the field? Or do you just say “I’m gonna be a programmer,” learn some code and the basics of a few languages and say “I’m a developer now”?

It can be really discouraging to hear “well if you don’t know xyz, then you’re not a *real* developer.” Who determines what “xyz” is?

What do you think?
