For me, when I had it (I have since crawled out and am merely underconfident, scared, etc), the feeling is "I am secretly not nearly* as good as people think I should be and therefore as people think I am because they don't look closely and if they did then they'd find out so wow I hope they don't look closely good thing people are usually content with surface thought hahaha but really oh god".
*understatement
This makes sense. And growing to overcome these feelings? Have you done anything specifically? or did it shift over time?
Your job, should you choose to accept it, is to comment on this thread explaining the most awesome thing you've done this month. You may be as blatantly proud of yourself as you feel. You may unabashedly consider yourself the coolest freaking person ever because of that awesome thing you're dying to tell everyone about. This is the place to do just that.
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do". Not "are working on". Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods.
So, what's the coolest thing you've done this month?
