For me, Curable is a nice little resource to have available at all times in an easy and quick format whenever I need a boost, whether it's a podcast article, a reminder of the basics, a writing exercise, or a meditation.
I do think that for anyone new to the concepts it's an excellent program, more structured than Alan's program, easier than Unlearn Your Pain and more up to date than our SEP (you get what you pay for!). And the annual cost is less than a visit to a PT or an acupuncturist or any specialist.
