The last three Christmases I have published “Pearls of Wisdom” – short compendia of wise words on CSR/green business/corporate responsibility. The first two (2009 and 2010) were compiled from contributors to The Green Executive and Vol 3 last year was crowd sourced from your good selves.

This year I’m doing the crowd sourcing again. I’m after real insights for readers – no platitudes or clichés, please – and this year we’re going to impose the ubiquitous 140 character tweet limit.

Feel free to submit extracts from your wisdom published elsewhere as long as you own the copyright. Contributors who make the cut will see their wise words in a pdf document similar to previous years, along with their name, organisation and URL. Editor’s decision is final (and power goes to my head).

So, clever people, get your thinking caps on and e-mail your entries here before 30 November.
