Skeptics: Is there a belief you hold on to despite that there is no evidence? (See details)

I’m speaking mostly to the self-proclaimed skeptics of the community (you know who you are). I’ve believed in a lot of things in my life, such as theosophy, God, horoscopes, accupuncture, aliens, and ESP. The list is much longer than that but in the last 15 years or so I’ve thrown out all my non-evidenced based beliefs and now I’m a pure through and through skeptic. But I know many skeptics who believe in God, and that’s fine. I’m interested, though, among the skeptics if there’s something that you hold on to, despite no real evidence. I have one thing, but I’m a little embarrassed by it, so I’ll hold off on answering to see how this question plays out.

So, skeptics, what belief do you hold on to? Why do you hold on to it?
