What is your Weird poker belief that seem to manifest and show up a lot?

I also have this thing where I say the hand you win with now, is the hand you will lose with next. Similarly the other way around. What you've lost with now, will be the winning hand next when you have the same cards. (not suited examples). Ie, you play 67 and you get the bottom part of a straight and someone else has a jack. and he takes you. the next time you have 67, some how magically it turns out to be the abaolute nuts. I've seen this soo many times.. anyone else? or what's your weird thing?
