Agreed (although still appreciated, TOD)! I could easily be wrong.

The evidence I would call on to support my belief are that:

• I spend more time actually working on stuff than I used to,
• I get less flustered in situations where others' perception of my intellect could suffer a hit (presentations, meetings, group conversations),
• in discussion/argument, I feel less concerned whether or not I come off as intelligent,
• I've observed fewer people telling me that I'm smart.

I can think of alternate explanations for all these observations though. I'll ask folk at our next meetup whether they think this is accurate, and I'll also ask a few people that have known me well for the past few years. The outside view is clearly more reliable here.
