Fruitfulness and multiplication rest on the command of mastery. If we fail to subdue our propensity to excuse ourselves (“it’s not my fault, the woman told me to do it”, “It’s not my responsibility, the serpent told me to do it”) we’ll continue as we always were. Worse still, we’ll diminish in our own eyes and hide away in a fig leaf life.
Purposeful productivity is really the mastery of time and energy in positive productive ways that bless mankind.
At base, I think it boils down to simply saying yes to the things you know you need to say yes to, and no to the things you don’t.
It comes down to the mastery of that moment of decision.
