Easy. It's kind of a reward for accomplishing "real" work. Not really an excuse, exactly, but I use it as justification.

I have 20 lab reports left to mark. I had 30 originally, and I have done ten of them (took me an hour to get started this morning, thanks to the Board!). It's time for a break. There will be another break after the next ten! One catogory per break. I did Questions about Words this morning, now I am in Miscellany, and later I will look at Wordplay and Fun.

Luckily I don't do this at home or my husband would never see me! Only my schoolwork gets this honour of having a rewards program with performance tied to Board visits!
