This is a great post. The author bridges together multiple loosely related, well understood concepts into a coherent whole with a simple conclusion; focus on just a few (1-3) things and do them well. It presents reasoning for concepts we understand so well; first and second systems, contextual boundaries, tight scope. Highly recommended read.
