Every time I make substantial extra money from the district -- like my summer school money -- I set aside a portion of it to do something fun and meaningful. In the past it's been a computer specially set up to make my life easier, and once it was my file server. This year it is Macie, a beagle puppy, and I'll be blogging about her at http://www.kweaver.org/macie
I think that doing something like this is good for recharging your batteries. In years past, the extra money has been for things like teaching an extra class which took a lot of energy. I also know that other people in my building do the same thing. One of my coworkers put a heater in her pool for example. It's a tangible reward. For example, my principal even said in his summer school introduction, that he was using his summer school money to take his family to Disney (I think the Florida one) in the winter. I think that is really cool since the whole family is losing him for most of the day during the summer, and I think he usually spends a lot of his summer with them doing sports.
