I have tried to update since your announcement.  Iam still unable to do
it.

Explaining to someone who does not want to understand is useless.  First
there must be the motivation to understand to put the effort to do it.

A good motivation would be to show people how to solve the problems they
have.  Of course that your examples do that.  But until a person knows
how it works, they will not be able to understand how it applies to
their personal problem.  So the solution is to find their problems,
choose one and show them how to solve it.  If it is easy to implement
for that person, it will connect with their motivation.  That will help
them put the effort into learning eev (or any other thing).  eev is just
a tool.  You learn to use a tool when you see the end result in your
mind.

Learning is hard.  Only some people like to learn for the sake of it.  
Most people try to avoid doing hard things.  They would rather be
connected to virtual reality and have it solve everything for them.

Very much.  Of course that I had to read it from the end to the
beginning to understand it better.  It would be more clear to me this
way:

***
Suppose that you have a cheat sheet about things that your are currently
learning in a file called ~/LEARNING. You could have:
`M-x le' and `M-2 M-6 M-j' open ~/LEARNING in the current window, and
`M-x ll' and `M-2 M-7 M-j' open ~/LEARNING in the window at the right.
You could do it by just runnig this: 
   (defun le () (interactive) (find-fline "~/LEARNING"))
   (defun ll () (interactive) (find-2a nil '(le)))
   (defun eejump-26 () (le))
   (defun eejump-27 () (ll))
***

Described in that order, I found motivation to learn it before the
explaination of how to do it.

On the other hand.  Short descriptions make better tools than deep ones.
 In case someone wants to dive in deeper, they could investigate.  The
important thing is the motivation.
