That's a very good write up. The dichotomy he describes between motivation and discipline is something that gradually came to me during my career. And some of the techniques he describes for "tricking" yourself into developing greater discpline are things that I sort of stumbled upon through trial and error. It would have been great to read something like this years ago, although at the time maybe I would not have realized its value.

When you've firmly established a new facet of discipline to the point that it is internalized and becomes automatic, that's when you've got a new beneficial habit. I like how Ng nails that in an almost understated way.
