A bad habit: Getting all the domains!

I have this horrible habit, where when I have an idea, I usually start by ordering a domain. And when I'm brainstorming, I might come up with around 30 ideas for domain names of a particular idea, which I narrow down to about 3-5. But horribly, I can't decide which one is the best (some people tell me it's because I'm a "libra"), so I end up buying all of them.
