Discussion on: How do you deal with imposter syndrome?

I have this a lot. I've started trying to track how I'm talking to myself, even outside of the moments where my stomach sinks. A lot of the time when impostor syndrome feelings are running high, I have something in the back of my head calling me names and making statements that basically say I am not able. I try to tell that voice to shut up, and I argue with it.
I think I need to do some work on why my performance at my job is such an important part of my self-esteem. Work is just work, but it feels like more than work.
