Now that's an interesting discussion. Have just read a fascinating book on change, called Switch by Dan and Chip Heath. Some great stories on how change was implemented by organisations and individuals. (Lovely story of how one guy showed Vietnamese villagers how to improve the diets of their malnourished chn by simply utilizing what was already available and a simple change of habits)
In order to implement change you need to appeal to both the rational and emotional side of ppl's brains. I guess its a difficult process as there has been heaps of stuff written about it. Sometimes it takes a bit of time, convincing ppl of the need for change (or if there is?) and then breaking old habits for new.
