Yeah, why not give it a try.

I like the following attitude:

"Can we rely on it that a ‘turning around’ will be accomplished by enough people quickly enough to save the modern world? This question is often asked, but whatever answer is given to it will mislead. The answer “yes” would lead to complacency; the answer “no” to despair. It is desirable to leave these perplexities behind us and get down to work.” E.F. Schumacher, Small is Beautiful

Nice one - that sums it up pretty well.

Personally, I like:

It's far too late and things are far too bad for pessimism.

Nice quote.
