I took a trapeze class a couple months back that was pretty damn terrifying, but I got through it and had a pretty good time.

In January, when I got all excited about Webfinger, I proposed an Ignite talk on it to RailsConf in Baltimore, before I knew anywhere near enough to talk on it. They accepted, so I was forced to learn enough to talk about it well and get others excited about it. Also damn terrifying, but way way worth it.
