Not masturbation, although you can brag about that if you want I guess.
This is the thread of things you've done well enough to surprise yourself.
I just learned that I set a new lap record for my class at Charlotte Motor Speedway during that race back in August. No one racing in my class of car has ever gone as fast at that track. I'm as shocked as anyone.
Of course the people running the event had the car under my father's name, so he gets credit. At least I know it was me.
So what have you done that made you pretty happy with yourself?
