Martin Couzins on modelling behaviour:

If you are the one who is trying to encourage others to try something out then a good place to start is to model the behavior ie actually use the tools and techniques you are helping others to adopt.

The bottom line is that by doing and being (and enjoy doing/being) what you are asking others to do you are giving everyone a chance to see what that behaviour looks (and can look) like. People see and hear if you feel good about something.

Be the change you want to see. One of the reasons I never stopped blogging during my time doing editorial development work at RBI was that by doing what I was asking others to do, I was both leading by example, and proving that I could find the time to do it while having a demanding job – so they could, too.

Telling without doing is never very persuasive.
