I don’t think there is a single solution for maximizing how much of your brain you use. I think it’s a combination of many factors (there are many ways to influence the brain). Here are the key factors (I think) that determine how much of your brain you use:
- Exercise: how much exercise? What type of exercise? Frequency of exercise? Variability of exercise? Heavy or light? Endurance or strength? Balancing/coordination? Flexibility? Hormone-stimulating exercises? Walking? Running?
- Rest: how much sleep? Naps?
- Mental stimulation: reading? Writing? Debate? Games/puzzles?
- Food: fresh foods? Cooked or raw? Meat or no meat? Carbs or no carbs? Nutrient-dense? Fasting?
- Supplements: caffeine? Supplements that promote the flow of blood to the brain (e.g., Gingko Biloba)? Green tea? Black tea?
- Nature: how much time spent in a park? Frequency?
- Stress: no stress? Moderate amounts of stress? Massage? Foam roller? Body work?
- Music: how much? Classical or other?
- Social: lots of socializing? Lots of friends? A few close friends?
- Positive attitude: how to keep positive and motivated? Laughter? Smiling?
- Goals: short-term goals? Long-term goals?
One thing that I am fairly sure of is this: the body and brain adapt quickly. A strategy that works today for stimulating the brain will likely not work next week or next month. Constant change is crucial. Also, it seems that each human is unique. What works for me may not work for you.
