I always get a good laugh with Mr. Robbins. Any activity framework (which is all he provides IMHO) can be useful in managing our emtional contraints (I believe the Greeks were right and much of our personality is gentically passed on to us by our parents) that hijack our intellects ("I don't know why I keep doing this stuff" type of thing).
I wouldn't forget my time in the org. but accept it and acknowledge its accumulated effect (I still snicker arrogantly when I meet other people calling themselves christian!) on my biases, thinking abilities and action abilities (Tony's specialty).
It is part of your life experience and can be used in your personal development as you re-formulate you life-philosophy. You are the only one that can hold you back. Use Tony by all means, but slow, painful thinking is unavoidable in the long run. But it is worth it!
