Extemporaneously:
(done, spoken, performed, etc., without special advance preparation;impromptu).
That is how I write to you every day.
I sit down at my computer, fill in my Quote of the Day, listen to and share with you my Minute with Maxwell and my Darren Daily and after updating the day and date I start typing whatever pops into my head. 
Sometimes as I begin this process, I remember a thought that I may have had or a tidbit that I wanted too share with you. 
Every once in a while, there is a day like today where I sit and stare at the screen and think to myself "I got nothin' today!"
Most times that occurs when my mind is looking ahead to what I want to get started on or how I want to go about getting my day underway. I just got a phone call asking for a favor.
It means carving out about 3 hours in the middle of my day to accomplish this task.
It really is no imposition, it was just unexpected and my mind needs a few minutes to revise my plans. 
It's like when I use a GPS (which is rare) and I miss a turn. There is that voice that comes on and says "recalculating!".
If I do not pay attention, the voice keeps repeating "recalculating....recalculating....recalculating" until I get back on course.
As I look ahead to the rest of my day, I find myself doing just that....recalculating.
I know what I want to accomplish today, (read:I know where I want my day to go) and now I must follow the map and the instructions to get me there.
 When I am in my car, I am never a big fan of back tracking.
I keep moving forward and plan out a new route.
How often do I see a driver who has missed his exit backing up on the highway.
There is no backing up on the highway of life.
If the speed limit on that highway of life is 55, I can't slow down to 35 while I try to figure out my next turn.
So now I am off. And as my GPS used to say to me..
"it's time to put the peddle to the metal!"
