It's interesting for me, to notice from my position as an e-learning consultant, to extricate the "learning and skill building" theory that is utilized in the ILP Kit.

The ILP Kit - and I suppose most of the self-help kits out there - start from a very valid position for adult learners.

1.  Adult learning needs to be task and pragmatically based.
2.  Adults "choose" what they wish to learn
3. Self-directed

What really grounds learning and skill building for adults is small group interaction, as well absolutely relevant feedback. 

In most self-help modalites, this feedback aspect is simply - missing.  There aren't any "sounding boards" to adequately measure whether your meditation is improving, whether the usage of the physical exercise is going the right way, etc. 

I've thought that I would be able to make quite a decent living, developing the "after the training" parts of a self-help training curriculum. 

And this is definitely true in the case of ILP Kit DVD as well. 

Examples -

For the physical exercise training - there are task-based activities, but not percentage based assessment tracking.  Including this would be pretty simple - some type of broad measuring stick response, that would also go along with 2nd order assessment theories.

For the one minute modules especially - which are already on shaky ground from what is known about skill building on a physiological and the attention level - these type of included feedback forms would be a great help.
