I had many problems related to what you mention there. Long story short: some years ago I got to my nation's newspapers because of my own small game studio and of my work on the local game dev association, and I got to speak to lot of conferences with very prestigious people, but I always felt empty, and I always felt I was more and more of an imposter. I rushed doing activities not because of my interest on them, but because of how they could help maintain and enforce my own image... and so on and on. Also I actually was starting to feel more and more stupid, because I wasn't doing the things I love most, and that I think I need to feed my mind.
Finally I decided that was stupid, and I decided a first step to find myself would be to shut the mouth up. I stopped caring a lot about press and related stuff, and despite I eventually did some note most of the times I sent the media to colleagues that I felt cold talk better than me about the different subjects. I dropped out from forums and disappeared from communities which only helped my ego grow. I just kept working quietly with a few clients, and I even started filtering my clients only to do the most interesting projects, which could again give a boost to my brain and let me feel again that I was doing something worth, and not just something that gave me money while making the others feel I was actually worth.
This was a lot of time ago, and that was like a slow career reset for me. These days I'm much happier about my work, while being a lot more slow profile (now I'm rarely called from the local press, as a remnant of my previous career, and because of my current activity I'm now teaching and giving some conferences).
But I think I have a lot more to learn yet. I loved your article, and despite all my growth in the latest years, I found interesting ideas in your article which I think I could use to improve my life a lot more. Thanks again.
Only wish I had read this some years later (the more years, the better).
