Note from the Editor: Irreplaceable

I am irreplaceable.

I want to be irreplaceable.

I want to believe that I am irreplaceable.

I want others to believe I am irreplaceable.

But the graveyard is full of irreplaceable people.

And   I hope and wish that at least some of things that I did – or to which I contributed – will not stop when I am no longer there.
So how can I reconcile this fervent grasp for irreplaceability with

this knowledge that I am replaceable

and this hope that I will indeed be replaced?

Looking forward to some advice – from readers who do and readers who completely don’t recognise this train of thought.
