I reviewed A Guide to the Good Life: The Ancient Art of Stoic Joy at my blog ("Modern Stoicism – The Good, the Bad, and the Ugly"). It's a philosophy book that's focused on being actionable, not just a historical survey, but I think it too-casually brushes off some of the unpleasant side effects of stoicism.
The desire to employ your Stoicism on a higher difficulty setting, coupled with the habit of seeing other people as obstacles can make you care less about other people. You root for them to be worse then they are. I used to wish that a girl who had only insulted me might try to hit me, so I could maintain my equanimity in the face of a bigger provocation. If a middle school bully mellowed with age, I would be a little disappointed, as my short bus ride was now wasted time, instead of a training opportunity.
You can't control whether or not the girl will hit or insult you. As a result hoping that she would do one of those things goes against stoicist ideals.
It's much better to seek out-of-comfort zone experiences where you can control that you have the experience. Instead of depending on the bully in the bus to provide an experience in which you can grow you can go and have fun dancing in the bus.
A year ago I was in a personal development seminar that's partly about improving one's charisma and finding the courage to do what one likes.
At the end of the day ...
