One question is, what is THE TRANSFORMATION you want to provide participants of your eCourse?
Once you know that answer, you can ask yourself what the best way to get them there is.
My suggestion is to write out ALL the modules and individual exercises you can think up, as they surface (because I’m sure more will surface) and then carry on with the friendly wizard. More clarity will come.
Don’t worry about choosing THE IDEA. That will become clear.
Happy for the clarity you have so far though. Great work.
