Procrastination

Why is it that I'm sat at my computer at 11 o'clock on a Sunday night when I have a full day's teaching tomorrow?
Why is the work I started over an hour ago barely touched? Come to that, why did I only start it just over an hour ago even though I could have done it at any time over the weekend?

This is not a long post (after all, I must get on with that work), but it's something I must get down. I was thinking the above thoughts when it came to me - I'm really good at procrastinating! Whenever I have jobs that must be done, but aren't much fun to do, I manage to leave them as late as possible before doing them. Sometimes, I leave them even later than that! It wouldn't be quite so bad if I was doing something useful instead, but I rarely am.
Having identified this flaw in my character, which I suspect my wife will tell you she identified years ago, I think there's only one course of action open to me...

But I'll worry about that tomorrow!
