My mother once commented that between sins of omission and sins of commission, she would choose sins of commission every time.
The implication was that when you make a mistake by acting, its lessons sink in as surely as barbed wire.
But when you make a mistake by failing to act, the parameters of that failure are blurred and uncertain.
I don't think this is a vastly-important point since exceptions can be found at every turn, but it has a broad-brush fitness in my mind...even in the face of beard-stroking observations that action and no-action amount to action.
With attention, any sort of action comes up a winner, but if you're as dumb as I am, sometimes a sharp kick in the pants helps.
