> Imposter syndrome is not about "fake it till you make it". Overcoming imposter syndrome is realizing that you have made it.

I'd have to disagree here. Impostor syndrome is an emotion. People overcome them in different ways. Mike's and yours suggestions are just two different solutions. The way I overcome it is by mentally preparing myself for the emotion and having a plan on how I can overcome it (ie - writing tests, working on a smaller problem, etc).
