Goes to my head

I’m worried that my recent spate of mini-successes is going to have a dark lining. I’m not worried like George Costanza that if I get too happy “God will kill me.” It’s more that I’m afraid I’m arrogant and conceited enough. I already talk too much. I already think quite highly of myself. As I’ve started to see some of my longer efforts come to fruition, I have begun to revel in the validity of my own ideas and intentions, and I’m verging on becoming an insufferable prick.
What to do? What to do? Air my dirty mental laundry in public, I gather.
