That is one of the first things I try to teach new ECOS club members on my campus (Environmentally Concerned Organization of Students). While I need to practice what I preach at times, the general idea is to empower people and make them feel good when they make a positive change, this will guide them to make positive change. Ridicule or pressure rarely puts anyone in the mood to adapt to your opinion. Then there are those who will not change and jump at the chance to ridicule, berate and belittle those who are making positive changes. Those people are not worth wasting your time with. Focus your energy on those who are willing to listen as they make up a much larger pecentage of the follower/leader group pool.
