Many moons ago when I started moving towards technical writing from a full time job as a web dev, one of my first posts was about this particular syndrome.

You mentioned there 2 points I talked about.

The weird thing that worked for me, and how I faced the syndrome…

Was accepting the fact that I was indeed an “imposter”.

But “they” would have to do a very good job at trying to “catch me” cuz I wasn’t gonna make it easy for them to do so.
