Ever consider you don't ever want to do or try something that other people write on their lists to do?
I'm all for new experiences, but some of my "don't care to ever discover for myself" list:
Join the Polar bear club
Climb Mt. Everest (Most anything to do with deadly nature.)
Go into outer space
Go into a sub into the deep ocean
Learning to spit fire
Most of these would be very extraordinary experiences, but would be very much not inclined to do. I'll wait for the movie/book.
Sometimes the easiest way to figure out what I want to do, is to cross off what I don't want to do first.
