I totally agree with you as making massive changes all at once is very hard since our lives have daily challenges of different sorts. We have coped with these challenges in some form or another, even if not too successfully.

The baby step is more likely going to be successful, but I believe persistence and continuity will make the difference in the end.

I find that programs like ES and others of similar nature teach us how to live again as what we learnt along the way did not prove to be helpful. If it had been, then we would not seek personal development programs.
