Some time when you're feeling important,
Some time when your ego's in bloom,
Some time when you take it for granted
You're the best man in the room;
Some time when you feel that your going
would leave an unfilled hole,
Just follow this simple instruction
And see how it humbles your soul.

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

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

The moral of this is quite simple
Do just the best you can,
And as you do, remember;
There’s no indispensable man
