1. I will try to drink mainly water to reduce my expenditure on drinks.
2. I will try to eat fairly cheaply without letting my diet fall to crap. Last year I did not limit myself on grocery expenditures and spent about $108 on food. I'm pretty sure I can drop this to $90. I might try to eat some food that's been on the shelf in my house for a while.
CAVEAT: I am exempt from these rules if I get a flyout. A flyout is basically a day long interview/campus visit for a university that is interested in hiring me. The exemption lasts from the day before I leave until the day after I return. At my discretion I may make up for these days by extending these rules into March.
...and by the way, I realized that I have a multi-day teaching conference to attend in February that's a couple hundred miles away...I'm going to allow gas for that.
