Hypomanic?

I think self-diagnosis is generally annoying, but I think I am hypomanic.

Here is a simple definition:

People with hypomania are generally perceived as being energetic, euphoric, overflowing with new ideas, and sometimes highly confident and charismatic, and unlike full-blown mania, they are sufficiently capable of coherent thought and action to participate in everyday activities. One in the state of hypomania might be immune to fear and doubt and have little social inhibition. They may talk to strangers easily, offer solutions to problems, and find pleasure in small activities.

John Gartner's The Hypomanic Edge (Simon and Schuster) contends that notable "Americans" including Christopher Columbus, Alexander Hamilton, Andrew Carnegie, Louis B Mayer, and Craig Venter (who mapped the human genome) owe their innovativeness and drive, as well as their eccentricities, to hypomanic temperaments.
