Planning to have no plans

I have too many plans. Plans within plans and around other plans. I am overscheduled in a way that isn't fun or exciting, it's just too much. I want to be able to say "yes, I'd love to" when the inevitable last minute thing happens but I am trying to get a feel for what that last minute thing may be ... and "we don't really do that" was the answer given.

Oh to be so abstract random in my schedule. I aspire to it, but somehow it never happens.
