"I am only one..."

The following is quotation from Edward Everett Hale, in a volume entitled 'Masterpieces of Religious Verse' (Thanks to University Librarian Diana Vogelsong for the reference. It has hung over my various desks at AU for more than 30 years. It seems worth quoting as a counterpoint to my two notes on 'drift to low performance' just written.

I am only one,
but still I am one.

I cannot do everything, but I still can do
something.

And because I cannot do everything,
I will not refuse to do the something that I can do.
