INDISPENSABLE  ADVICE

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 person in the room,

Sometime when you feel that your going

Would leave an unfillable 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.

The moral of this quaint example

( As quoted by poets anon..)

Be proud of yourself but remember

There is NO INDISPENSABLE ONE.
