I weeded my collection mercilessly. I got rid of three whole boxes.
One of the books I got rid of was 'The Complete Klutz's Guide to Juggling'. I pulled it out because I lost the three little beanbags that came with it. I figured that if I hadn't learned to juggle using a substitute for the little beanbags, that I'd probably never bother to use the book at all.
So yesterday, when I found the little beanbags, I decided that I need to go back to the used book store where I'd sold my three boxes of books and buy my juggling book back.
Because now I'll learn to juggle for sure!
