I'm starting to collect a few of those. I now have things in the evening on Monday, Wednesday, and Friday. One of the strange things is that the hours and days pass by very slowly, though the weeks and months go pretty quickly. When I worked, I was really busy all the time (managed a software engineering organization), and there were many things that were regularly scheduled each day. I don't want to get back to anytime like that, but it also feels like an eternity between Monday and Wednesday.
