INDISPENSABILITY

Desk sign at St. Louis Office Supply Company: "Don't be  indispensable. If you can't be replaced, you can't be promoted."

Sometime, when you're feeling important,
Sometime, when your ego's in bloom;
Sometime, when you take it for granted
You're the best qualified man in the room;

Sometime, when you feel that your going
Would leave an unfillable hole,
Just follow this simple instruction
And see how it humbles the soul.

Take a bucket and fill it with water;
Put your hand in it, up to the wrist;
Pull it out; and the hole that's remaining
Is a measure of how you'll be missed.

You may splash all you please, when you enter,
You can stir up the water galore,
But stop and you'll find in a minute
That it looks quite the same as before.

The moral in this quaint example
Is do just the best that you can,
Be proud of yourself, but remember-- 
There's NO indispensable man!
