Just a thought.
It seems to be that there are many companies trying to develop that one program/tool that will answer everyones problems in life. There are as many ways in approaching problem solving as there are individuals in the world. If we were robots it would be easy to say use this then this and after that this and you'll be running smoothly. Although in one sense LSC has already created some packages in Ideal Mindset, Decisive Action or Consistent Achievement. These are each a selection of paraliminals with coaching to help you to reach your goals.
Just like everyone like to drink something different and at different times of the day. Self help programs will each work best at different times of a persons life. So it remains pretty hard to say this first and then this from the selection of self help tools that LCS has already created yet they are all useful and work.
If there is any course that I consider foundational, a starting point when you don't know exactly what tool will help you best I'd say it is Natural Brilliance. In my opinion this course sets the basis of getting out of ruts. It makes the other courses so much easier to impliment when you learn to Release, Notice, Respond and Witness what is currently going on in your life.
