I really liked your report of the scientology class. The conclusions, not so much. Many LW posts (including some of mine, too ashamed to link here) follow this pattern of giving a wonderful convincing anecdote and then a big flimsy over-generalization on top. Perhaps we could institute a norm that posting anecdotes without making conclusions from them is okay. I took some boxing lessons, still cannot fight but no longer fear physical confrontations, and that's all. I learned to draw using a book by Betty Edwards, it was easy and fun, and that's all.
