Many years ago, I read a self-help book and did an exercise in it. You were supposed to write down 100 things you would like to do in your lifetime. Somewhere in there I wrote "Play in a band".
I honestly have NO memory of writing that, or even wishing that in the past. I suspect I was digging deep to come up with 100 things to list.
I put the list away and promptly forgot about it. About 10-12 years later, after my divorce, I ran across the list. I was shocked to see that I had written that there - because in the meantime, I had learned to play the drums and had joined a band!!!!!
