Nothing new under the sun. No worries.
Here is a great oldie:
Sometime, When you're feeling important
Sometime, When your ego's in bloom
Sometime, When you take it for granted
That you're the best qualified in the room
Sometime, 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 you'll be missed.
The moral in this quaint example
Is do just the best that you can
Be proud of yourself but remember
There's no INDISPENSABLE MAN.,
