You know when you sit in front of the computer in the morning and say to yourself "today I'm going work on this project and that and also this other thing and maybe at the end of the day I'll go outside and paddle/bike/swim/run/whatever" but then after about the first 2 minutes of contemplating all that you will accomplish in the day, the phone rings ...
..and you find yourself doing nothing all day (and night) but putting out fires hither and thither? Gosh, I hate days like that!
But I guess those days make life ummm, interesting ...
