It might come as a surprise to learn that the brain responds to training in much the same way as our muscles, even though most of us never think about it that way. Clear thinking, focus, creativity and good judgment are built through challenge, when the brain is asked to stretch beyond routine rather than run on autopilot. That slight mental discomfort is often the sign that the brain is actually being trained, a lot like that good workout burn in your muscles.



most people who engage in mental and physical exercise are… wealthy. they have the leisure time and resources to do it.
most people… are not wealthy so they don’t have the time or resources to do this.
