You must do this if you want people to change...

Sometimes I post things here as a reminder for myself. This should be one of those occasions.

In theory, it should be a post I go back to often. 

Just to remember.

The memorable lesson which sprung to my mind due to this post?

If you're going to ask people to change you need to tell them two things...

1 - Why the change will be for their benefit and
2 - What staying in the same place will cost them.
