it's not enough.

This is all there is, and it's not enough. 

It might do to let you know I'm hanging on.

I'm like that man who carried a brick around with him

To show the world what his house used to look like.

 

[Bertolt Brecht {1898-1956} 'Motto' {trans. by Michael Hofmann}, from
Twentieth-Century German Poetry: An anthology]
