Recalculation is something I apply to my personal weekly agenda when I am given an opportunity to do something special with my family or friends. I don't want to live so rigidly that I can't ever accept a last minute invitation. My family members are very spontaneous and it's very common for them to decide just moments before that they're going to go to the movies, or for ice cream, or pretty much anywhere. I am not very spontaneous myself, but flow with people who are. My husband has decided at the last minute that we'll go away overnight. Taking advantage of any of this requires an immediate recalculation for me. It's important to me to work it out if at all possible because I want to enjoy life and do things with those I love.
Looking at my agenda, I see what could possibly be moved to the next day. If a change is possible, I make a decision to add a few things to the following day's agenda in order to get it all done, and on time -- by Sunday. The most important thing with a recalculation is that you don't put it off again and absolutely follow through. (This is the stuff leaders are made of, by the way.) It's tempting after recalculation when I have ten items to acccomplish the next day instead of five to just keep putting them off, but that would eventually lead to greater stress not to mention bad character.
A recalculation does no good if you don't actually arrive at your destination by week's end. The step where most people fail is the follow through to actually add the deferred items to the next day's schedule. I have to be honest that it does drive me a little
Through careful recalculation, flexibility and follow through you can get your work done and spend time with those you love.
