I just learned after all these years that I am an ENTP (according to those wacky psychologists). My favorite analysis of ME: "Both at work and at home, ENTPs are very fond of "toys"--physical or intellectual, the more sophisticated the better. They tend to tire of these quickly, however, and move on to new ones. "
Perhaps more telling though is that I share a birthday with Lizzie Borden, Rasputin, George McGovern, Samuel Colt, Atom Egoyan, and Herbert Marcuse.
