James Clear is an incredible marketer. I blogged about the same stuff ten years ago and read books covering all the same material at the time as well. The only stuff I actually learned from James Clear was a few mnemonics, i.e., there were a few times he rephrased existing knowledge in a way that was easier to remember.

Mostly, though, he is just fantastic at marketing. He's a good writer, but that's not the thing to learn from him, in my opinion. He has email lists, a podcast strategy -- I forgot the rest but he gets deep into it.
