Does Impostor Sydrome Go Away?
NO! But we can learn to not be controlled by its. Recently I was thrust into a new position with and assigned a leadership role. Armed with only my wits and a smile I had to prove to the team that I was not going to drag them down. But first I had to prove it to myself. This wouldn't be the last time I would sit in my car outside the office and try to convince myself not to just give up and drive home.
I have been developing in high pressure environments for 10 years in multiple languages and frameworks that deliver exciting content to millions of users around the world. I have led teams and successfully run my own company. One might think that all this experience would save me from Impostor Syndrome but it doesn't.
Some people say "Fake it until you make it". Don't tell that to your boss but I can't give better advice myself. A long time ago a friend told me, "Someone hired you and is paying you money, obviously they think you can do the work so just do the work." That is all that ever worked for me. I was never able to internalize that I was good enough, but to belive that someone else had faith in me was something I could not refute immediately and thus it gave me some solace.
The truth about Impostor Syndrome is its the nature of our brains to try and protect us from pain. Fear of rejection or failure leads some of us to flee from risk, there is nothing wrong with. You are the happy owner of a human brain and while it didn't come with an owners manual it is yours to train. I often think of my mind like a pet. If I treat it well and give it the right reinforcement I can make it do tricks. Externalizing my worth is a trick I have learned to help me avoid the debilitating feeling of low internal self worth.
Accept your weaknesses and learn to work with them. I hope this trick helps you be more productive and confident. If you have your own tricks I would love to hear how it helps you get through difficult situations.
Remember keep your eyes forward and keep working, I believe in you and you are doing fine!
