How did Andrew Ng become so good at Machine Learning?

I've read a lot of Andrew's comments, so I'll mention a few things that I've come across.

• He clearly has very high natural intelligence and a huge amount of energy.
• He's been at it for a very long time.  He was heavily involved in ML research as an undergrad, and may well have been working on learning AI/statistics/etc before college.
• Because he's been consistently exposed to the best (CMU, MIT, Berkeley, Stanford), he's been exposed to what it takes to do great work.
• He reads papers for two hours a day, which he says leads him to good ideas.  I've noticed that among ML/CV/NLP researchers, for a lot of them, you see them with an IDE open all day long, and they probably don't read enough.  Those who read more tend to have better ideas, and access to a wider range of tools.
• While his explanations are extremely lucid, this was apparently not always the case.  During his first year as a Professor, he got terrible teaching reviews.  He worked at it until he became excellent.
