#1 I was a straight-A student before my second year at medical school, but during that year, in the context of an escalating workload, my grades suddenly slumped. I struggled to understand what was happening. I was physically exhausted but didn't realize it until the vacation between my second and third years.

#2 The most important aspect of a good education is the ability to allow thoughts to congeal, which is what makes cognitive rhythm so important. When you think of great rhythm, you probably think of music or the amazing riffs of a guitarist like Jimi Hendrix.

#3 The brain has different waves that it uses to focus on different tasks. Beta waves are the focus waves, and they would appear on your EEG when your eyes were glued to whatever task you were doing.

#4 The focus and unfocus circuits are like a flashlight that can light up the path just ahead. They are designed to work together, but we often stop this natural connection in our brains when we overfocus.
