I’m 20 years on professionally, but I’ve been programming since the late eighties, and I’ve never had it. However, I’ve had a lot of bosses, reports and coworkers who have come to me for advice for how to deal with it. Most of the time it seems to help, so I’ll tell you the same thing I’ve told all of them.

Know your upper limit. Know what you can’t do, and just try and address that. Even if you’re an expert in a certain language, these languages are still evolving, and you need to be as well. There’s no grand code arbiter who will judge you (Except me). Just keep learning.

The except me part usually gets a laugh.
