Since I don't believe in luck, I will have to say that the STUPIDEST thing I ever did was marry my first wife. She was beautiful (I mean really awesome) and cool and was very interested in the bedroom. We were arguing for 10 years, then she left. It took me 10 more years to recover.
I would sure like to have that time back. What a waste.
But she was sure good-looking. The problem with marrying up is, if the spouse gets wise to it, you end up with a broken heart.
