Emergency supplies are needed in a disaster area. You try to jam them all onto a small plane, and the pilot tells you the plane will crash with all that weight, if it even takes off at all.
“The supplies have to get there,” you respond, ignoring the warning. Later, no supplies reach the destination at all.
You have so much work to do that you’re staying until 9, 10, 11 PM, and going in again by 7 every day. A colleague tells you to cut back on the work a little before you burn out.
“The work has to get done,” you respond, ignoring the warning. Later, no work gets done at all.
