Peterson is very good at speaking and lecturing (practice makes perfect!) and I enjoy his work. That said, his tack is largely an updated stoic philosophy. A good idea, don't get me wrong. Still, if you liked his book, I'd go back and read more about stoicism. Here are some suggestion, but if anyone else has others, please chime in:
