Indispensability?

When I read this poem for the very first time I was a school-going teenager. Over the years it has always kept me grounded. Sometimes things you read as a kid have the ability to influence you for life. For a long time I've been meaning to share this poem with you all. I guess that day is today....

Indispensability?
by Saxon White Kessinger

Sometimes when you are feeling important,
Sometimes when your ego is 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 unfillable hole --
Just follow these simple instructions
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 the measure of how much you're 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 -- Do the best that you can,
Be proud of yourself but remember:
There is no indispensable man!
