Today wasn't a good day. I'll summarize it thus: I've booked way too much time on the selfless side of the ledger.
I've lived enough years, and my remaining time is too valuable to be given away too easily. I have knowledge. I have wisdom. I have talents. I'm happy to share them with the right people, for the right cause. I will never again be, however, just a body to fill a slot and engage in mindless activity.
They who say such things, say, never say never. This is a never I'll say with absolute certainty.
