I've been thinking about time a lot lately – there just isn't enough of the stuff.  It seems like all I ever do is add things to my todo list but things don't ever seem to get crossed off.  What's up with that?  I guess I'm just interested in a lot of different things and there is lots I want to learn about and explore, but it's getting really frustrating that I can't get more done.  Or maybe I just get overwhelmed by my todo list – I look at the millions of things on it and then I just want to crawl in a corner and suck my thumb….
