This is a great question.

I lose my sense of the ground and in the thrall of such great happy feelings I unwittingly do dangerous things.

Hypersexuality to the point that sex to orgasm doesn't even dent the super mood I'm in. No falling asleep afterwards for me.

Something that I learned in my latest research is similar to other lists on this thread: I work at amping up the good mood! Hallo!? This is adding gas to the flame.

I also feel confidence based on my good mood rather than some increase in actual abilities or breech in the laws of probabilities. Dostoevsky says in The Gambler that you feel like you can flip your nose at fate!

I want to add lots more plans and I feel like merely thinking about them will bring them to complete and wonderful fruition.

I fantasize about how my tiny string of successes will roll on and on. So that if I make & post a short video made on a Flip camera, it will draw lots of attention—go viral. Someone of the staff at Sundance will catch wind, alert Robert Redford who will send his private pilot and plane to whisk me to Utah to discuss taking over the direction of a script he's been struggling with.

As a child I luvved Thurber's Walter Mitty character. "Please, a fountain pen someone so I can repair this aspirator and continue this operation."

I can compose endless song cycles in my mind (no music training). I hear Jazz and it's terrific.

I underestimate how many tiny frustrations I will have to cope with on my way to finishing something.

I am irritable: can't you see I'm in a good mood and you must fit what you do around that?! I guess I should keep apart from people.

But I don't want that. I want to connect to all my friends.

I don't want to do anything that's known to lower my mood, like paying bills, doing the dishes, taking out the trash, cleaning up.

I am super vulnerable to small disappointments crashing my high.
