If it's not...then there's really nothing "left" on the table — if ever turns out to be valuable, you'll probably come across it again, when needed.
I constantly get a similar feeling. I'm speeding around from task to task, just grasping enough to get the current task done so I can get to the next one and the next one...
And somehow this is value-creating? Apparently it is, but it seems almost accidental, at that rate.
I'd rather slow down and appreciate the value as it moves through me, into whatever I'm doing.
I usually get more from the process, at the same time.
