Skydive. I was in the Air Force. I don't jump out of a perfectly good airplane.
Teach in public schools. I tried it. I was a substitute teacher at a middle school -- for one day. During that day I did what the regular teacher instructed me to do, and read articles from a science magazine for kids. I found myself reading environmentalist propaganda. As I read, I mumbled a few interjections to the baffled students that contradicted the point of the article. That and the fact that I could not make them shut up -- "Um, could you guys, uh, be quiet? Hello?" -- ended my career as a teacher.
Have sex with a man. Nothing against homosexuals, but men do not excite me. Besides, I know what men are like. They would just use me for my body, then the moment they were satisfied they would be thinking about how they can get rid of me and even if some relationship did develop, they would watch football with their buddies instead of shopping for shoes with me. Why would I want that when I can do all that myself to a woman?
Watch "American Idol" sober. I apologize now to all you "American Idol" fans because I must be snarky. It's glorified karaoke. These crass people warbling in melissmatic excess to boring tunes that drone on and on -- it screams bad taste. It's like something dreamed up by Alvah Scarret in The Fountainhead. Goethe said we are what we turn our attention to. If Goethe is right, then those who watch "American Idol" long enough turn into mediocrities of limited intelligence that are incapable of understanding the finer things in life.
Be a Stand-Up Comedian. Now, this is different from the activities above. There's nothing inherently bad about stand-up comedy, it's just something I can't do, like sing opera or dunk a basketball. I have been paid to write comedy for radio morning shows, but no one would pay me to stand before an audience and tell a joke. The professional comedian has to look at the world in a skewed way. He tends to stick to surface issues and human foibles. I tend to think philosophically, which I believe Aristotle would have agreed means looking for causes. The philosophical way of thinking, when it is a part of one's character, habituates one to seriousness instead of looking for the humorous twist.
