You are correct. I did not write to you yesterday. When the day started out,I had every intention to write. As the hours passed,I found myself unfocused and by nightfall I simply decided to abandon any attempt to share my thoughts with you. My thinking was "tomorrow is another day!".
Well here it is ,yesterday's tomorrow and if I were to succumb to the way I am feeling energetically, I would not be sitting here writing today either.
It could be the residual effect of  my workout from yesterday. Normally on Saturday mornings I train with my trainer. Yesterday, instead, he became my workout partner. It was a fantastic experience,one that I hope we can do more often. Working out with a young man in his late 20's who until two years ago was playing semi-pro football, is pretty awesome at 61!Now if he could only keep up with me!
(JUST KIDDING!)
To be honest, I don't believe that's the reason for my apparent lethargy.I suppose I could ruminate on the why's of my apathetic mood, however that would really be of no help. 
While searching for a quote or thought of the day, I came across Steve Maraboli's quote which had been sitting on my desk top for a while now.It absolutely sums up where I am today.And what I must do to move on from this place.
Get out of my own way!
Stop the paralysis by analysis. 
Create a plan and move on!
The only part of his quote that I am not dealing with is "decide what you want".
In that I am not sure what I want ,I am choosing to keep moving knowing that eventually the darkness will pass and a light will once again shine in me.In fact, maybe that is the "what I want". I want to not be stuck here any longer. So my decision is to get.off of my butt and move on. 
There are times in the gym, where I find that I am encouraging myself to push through. Sometimes I am even scolding,yelling or challenging myself.Today is just one such day. I know I will be better off for putting forth the effort. And not a half-ass feeble simulation of effort. I mean a dig deep and find that extra effort. The kind that just showed up yesterday when I found myself trying to keep pace with some one less than half my age whose physical attributes are only something I can dream of having.
(No matter how much I work out or how much weight I lose, I will never be 6'4").
The message is clear.
Get moving....keep growing!
Like that extra rep at the end of a set, I know I will feel better for having pushed myself!
Shavua Tov!
