Nope. The closest I get is when I'm in a situation (usually if a sports context) where things are finally going my (or the team's) way after some problems, and I'll remind myself and my teammates not to get overconfident by quoting Han Solo. Great kid! Don't get cocky!
2. What extremes have you heard of someone going to in the name of superstition?
It was always funny to watch Sparky Anderson walk out to the mound to talk to a pitcher, because he had a superstition about stepping on the baseline. He'd always get his pace wrong, and have to stutter step as he got to the line so that he'd avoid stepping on it.
3. Believer or not, what's your favorite superstition?
That sex while in training for a sport saps your strength, because it's always been a good way of justifying my total lack of a sex life. Yeah, I'm not getting any, but boy did I ever have a great game today...
4. Do you believe in luck? If yes, do you have a lucky number/article of clothing/ritual?
Sort of. I believe that people can be lucky or unlucky, sometimes both. I have been very lucky in my life in some ways, and completely unlucky in others. I also believe that luck is a product of design, rather than from lucky numbers or hats, so that you have a better chance of being lucky if you've done the prep work to allow your lucky break to happen. For example, I totally lucked into my house. It came available at exactly the right time, was in exactly the right neighborhood, and was priced below market value. But if I hadn't spent the couple of years before that putting money into my savings account, I would never have been able to take advantage of that particular lucky break, so it wouldn't have been lucky for me.
5. Do you believe in astrology? Why or why not?
Not in the least, and I always boggle at people who take it seriously.
