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 you're going
Would leave an unfillable hole;
Just follow these simple instructions
And see how they humble your soul;
Take a bucket and fill it with water,
Put your hands in it up to your wrists,
Pull them out - and the hole that remains
Is the measure of how much you'll be missed.
You may splash all you please when you enter.
You may stir up the waters 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.
You must do the best that you can.
Be proud of yourself, but remember.
There is no indispensable man.
