Exercise: Find at least one thing which you do for less than perfectly noble reasons, which you are going to admit to everyone else in the study group, and not fix for at least a week. Everyone else in the study group will admit something similar to you. Possibly followed by group hug. (The idea isn't that any given flaw is okay, the idea is that it's okay to have a running accurate description of yourself which involves known flaws you haven't fixed yet, and all of you are in that same boat together.)

Could you clarify somewhat what you mean by "less than perfectly noble reasons"? What I think of as "things I do for less than perfectly noble reasons" is an entirely different set than "flaws I haven't fixed yet". The latter implies consideration only of things that you can, should, and want to change. This is in contrast to things I do because I'm not perfectly noble and being perfectly noble is not a goal.

I actually think confessions and acceptance of both of those kinds of deviations from perfect nobility could be valuable. It's ok to have an accurate running description of how you are and also ok to have an accurate running description on how you want to be.
