It occured to me the other day that although I drink coffee all day long, I never take coffee breaks.
Which is not to say I work all the time, but that usually I grab a cup of coffee and read or write blog stuff while taking 10-15 minutes off from whatever I'm doing. Or I grab another cup of coffee and drink it while I work.
I started making coffee at work because although my office building has a coffee bar out near the lobby, I'd go broke if I went and paid coffee bar prices two or three times a day. (Plus the coffee I buy is better than the Starbucks beans they use.) Yet making my own coffee also makes it easy to drink a good 3-4 cups a day, and doing it while at my desk, in front of my computer has the tendency to leave one with a mind-racing-yet-mind-tired feeling at the end of the day.
I'm not sure that I'm going to make any changes in these habbits at the moment, but it does occur to me that I'd probably actually be more productive if I wandered off and took a fifteen minute coffee break somewhere else, while talking with co-workers or playing a quick boardgame or reading a chapter from a book. Something that doesn't happen on an LCD screen.
