Study Motivation

It is stinking hot, and the last thing I want to do when I get home is study. It is hard enough staying awoke let alone concentrating and expending brainpower. The typical Japanese custom would be for me to knock back a beer while relaxing in front of the TV, but without a family to create noise I am likely to fall asleep and not awake until late evening. I crave the beer after work (if you ever experience the sultry heat of a Japanese summer you would understand this craving) but I know it will deal a killer blow to any chance of study. How to have my beer and study too? This is my solution - I have made the beer contingent on the study. 50 kanji equals one can of beer. Normally when studying kanji my mind can wander and I will stare out the window, shuffle papers etc, but with a beer as the prize for completion I have found new powers of concentration.
