Wikiquote explains here that the following is misattributed --

• I am only one, but I am one.

• I can not do everything, but I can do something.

• I must not fail to do the something that I can do.

I learned these word as a Helen Keller quotation, and I think of her each time I read them.

Beware the shortsighted quick fix that can lead to worse problems

The close-at-hand problem is always the one the defender must take care of before anything else, but the solution should include what you are committing yourself to over the long haul.

"It is altogether too easy to let the burden of the immediate problem obliterate other considerations from your thinking and to jump at what promises to be a quick fix. What often happens is that you have not achieved a long-range success but only converted one difficulty into another perhaps less obvious but no less onerous one.
