For those who haven't been through Discovery Training - I feel very sorry for you. For those that have been to Discovery, you know how great it is! I went through Discovery in April of 2008, and I can say without hesitation that it was a life changing experience. I can also say without hesitation that it's impossible to explain Discovery! About the best I can come up with, so far, is this: if you think your life is perfect, and you feel 100% comfortable in all of your interpersonal relationships, then you don't need Discovery. For the rest of us, it's well worth it.
If you do what you've always done, you'll get what you've always got!
