What are some approaches to prevent the following scenario from occuring or ways to rescue myself when it occurs?
Today I started out with a reasonable list of N/As, 15 small day-specific actions (have to be done today but not at specific time), and 6 true appointments. Enroute from one of the appointments, I saw an opportunity to get some of the N/As completed, in theory in one fell swoop and so I launched into them. What I thought would take 1/2 to 1 hour, took 21/2 hours. I was an hour and half into this when I realized that I had made this mistake but it seemed wiser (at the time) to finish all those in a batch since I had invested the time already. At the end of the two and a half hours, I realized that there was one more N/A I could do in that location. Again, not day-specific, but something that was getting stale on my list and would be a convenience to me since I am rarely in that locale, so I went ahead and did that. But, instead of taking 15 minutes, it took an hour but while there was a waiting time, so I accomplished two other actions that I am glad I did, even alhtough they were not on any list at all. Now, when I resume work in a few minutes (this is my little chill out time and I have to sit 2-3x a day with a heating pad anyway), I am going to be in crisis mode. I have 14 day-specifics to do, 5 appointments (1 hr, 1/2 hr, 1 1/2 hr, and 2 1/2 hrs) and there is not much of the day left!
