‘The Indispensable Man’

Sometime, when you’re feeling important,
Sometime, when your ego’s in bloom,
Sometime, when you take it for granted,
You’re the best-informed man in the room.

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

You may splash all you please as you enter,
You may stir up the waters galore,
But stop and you’ll see in a moment,
That it looks just the same as before.

The moral of this little story,
Is do just the best you can,
‘Cause you’ll find that in spite of vain glory,
There is no indispensable man.
