Often I get an impulse to buy random things, but with a little will power and reasoning I am able to overcome the urge. For instance just last week I wanted to by a bunch of pinball machine balls, but was able to resist. Yesterday however, inspired by the guys moving the 1300-1900 (maybe more) pound rock, I had an urge to buy books about building stone walls. And so I did. They look absolutely fascinating, and though I may never build a stone wall I am sure I will be happy to have read the books.
