Anyone have any regrets from their past

Only thing I can cop to is more a "I wonder what would have happened if?" type of thing.
I had a couple of opportunity's in my life where my path had forks in the road. I've often wondered what would have happened if I had went to Korea instead of Germany? What would have happened if I went to Ft. Polk instead of Ft.Knox? Then there was a huge one that involved a girl and me both way to young and stupid. That one I'm sure I made the right choice on, but I still wonder.
