I really feel for you. Where I work we have the luxury of having tv/vcr combos at our desk - so my biggest dilemma is what to watch before 12:30 and after 4:00 (I watch all the CBS soaps lol). Like everyone else said, balance your checkbook, make out a shopping list, pay bills, read the paper, organize your work email, your desk. Heck check out the websites I produce (for my job), and get some ideas for recipes or do-it-yourself projects:

www.hgtv.com
www.foodnetwork.com
www.fineliving.com
also, i like looking at
