Indispensable Man

I have had this poem around for ages and I think it says something important for all of us to think about. Not really a joke but since it is snowing outside this morning that is enough of a joke.

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

Sometimes, 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 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 of this quaint example
Is to do just the best that you can;
Be proud of yourself, but remember.
There is no indispensable man.
