"'If ever these was a time to be overextended, this is it.'"
to which I replied:
I prefer the term "engaged"
As long as I'm enjoying, and/or getting some mental gratification the project ... It ain't "work" if it's fun.
The modern world of communication/connectivity allows engagement in a multitude of projects, partnering with those with different skill sets.
This also allows enhanced cross fertilization of projects with application of ideas generated from one to another.
It also allows business as a non-zero-sum game.
You can end up with multiple winners.
Even a decade ago, this might be considered "overextended", today, it's only the ability to apply more mental energy, fire more synapses, keep more neurons busy.
But just wait till we can "jack in"
