Anything. Something it is good => build confident, make people make a first step on learning.
Something it is bad => scam … until someone believe you.
Confidence.
My career. I made it.
Edit for context: I never finished school, and as such I have no formal education in what I do. But I’ve always enjoyed tinkering with servers and networks. This coincidentally became highly relevant in this (seemingly very unrelated) job I had a couple of eons ago. After I quit I exaggerated that detail and used it to pretend I was a professional in my field on future job applications, and that worked out well… until one day I suddenly realized that I’m actually a professional in my field.
Today I can say that I’m good at what I do… but it’s (Mostly) a result of winging it and learning as I go.

You know when you’re nervous about something, and people say “just be confident!” ? Thats when you gotta fake it til you make it
