In a ridiculously reductive act of precis, I've summarized his summary of the rules; but they're good to keep in mind, so at the very least, typing this will help set them in my own long term memory.
- Exercise improves brain power;
- The brain evolves (it is a survival organ);
- Every brain is wired differently;
- We can only focus on one thing at a time;
- Repetition improves memory;
- Sleep is key to development and maintenance;
- Long term stress damages memory, executive function and motor skills;
- All of the senses assist memory, but vision is strongest.
Of all the books I've read on this topic, the ones I would most highly recommend are Thinking: Fast and Slow and The Brain That Changes Itself. The others are sprinkled throughout my library, and I can't think of one that I didn't enjoy.
