Exchanging custom Powerpacks for Self Help Books we read
The idea has two parts: (1) Making custom Powerpacks, and (2) Letting Allies download them.
For example, if I want to practice the "7 Habits" or "The Happiness Advantage", a Stephen Covey Powerpack, or a Shawn Achor Powerpack should be customizeable so that I can share it with my allies.
It is so much more powerful to be bound by a book/field of work. It gives meaning as well as structure to following a book rather than simply thinking of some day in the future when you will follow it up.
