Regret.
We act hoping we won’t have regrets for doing that thing. We incur stress that the things we do or have done are wrong; we hope that we are pleased with results of doing.
On the other hand, we don’t as often consider how we might be changed by not taking action. What if we said no? What if we allowed the status quo to be the status quo? Might that also change us?
It follows that we should consider the double negative: what have you NOT been doing that, if you had been, would have been a bigger negative?
Assess your plan from all angles and consider all possibilities.
