Stopping to smell the roses?

Of late, my focus has been channeled towards work, work and work.
I seem to have lost track of anything else which falls out of the boundaries of which I consider as work.
It's not so much so as the work which bothers me as much...
But when there is time to pull my head out of the water. A nagging feeling is there. Like a bad aftertaste lingering on the palate of my tongue.

Something seems to be missing, but I just can't place my finger on it.
This nags me to the point where...
Somewhere along the way I wonder if I may have left some part of me behind.

When I take a step back to think about it, it seems to boil down to two questions:

Is it...

What you DO defines who you are.

OR

Is it...

WHO you are defines what you do.

In normal circumstances I'd like to think that everyone would know the answer in a heartbeat.


Of late however... it doesn't seem that simple.
