Steven Covey's stuff is about developing 'habits' that can make us more effective in whatever life-goals we are trying to achieve. Alot of the stuff was derived from a 'business' model, and is a bit 'American' if you know what I mean- you'll find Covey's books in the 'Business & Management' section of WH Smith as well as the 'self- help' section- which made me quite resistant at first- but if you too harbour those sort of prejudices it's worth overcoming them and checking out his Seven Habits of Highly Effective People where you will find much that can be transfered to permacultural practice.
