It doesn't matter how desparately he wants it, or how much you or I or anyone else wants it. All that's necessary is to do the work. Meetings are great, but they're not enough. I wouldn't suggest anyone try to do the steps without a guide, that's what sponsors are for. No matter how full of it people with long term sobriety may seem, they almost always have experience working the steps and most will be willing to help. And yes, not doing the 4th, 5th, or any of the steps will just about guarantee relapse. But don't take my word for it, it says so in the big book. Sorry if I sound harsh, I don't mean to. These are, however, harsh truths. Went through a lot of pain finding them out!
