Intrinsic and Extrinsic motivation.
Is punishment a motivation...some thinks so...by using the threat
of punishment to push the soldiers to take their M16 to charge up
the hill, etc.
Fundamentally, most pple dun see imminent war, even if the doctrine
that war is unfathomable, unpredictable of its occurrence, we must
be prepared for it.
But day to day, under the strong sunlight, charging up the hill to
the happiness of the commanders who sip 7-up when u r charging up
is never near the whole idea of intrinsic motivation which is
acclaimed to be the way to go.
Something got to be done, croco dun know how
