As a mature woman I am always looking for tools on how to maximize and stimulate my brain power. This was a very informative post and video and gave me some great tips that will help enhance how I keep young at heart (or should I say young at brain). Two things that I found that really helped me have a clearer mind and helped with focus was taking sugar (glucose)completely out of my diet. In my case I use ketogenics which is replacing glucose with ketones. Amazingly my brain fog and focus improved 10 fold within a week. I will never put sugar back in my body again or sugar substitutes. I have a very clean diet. The other thing that you mentioned that I love is visualization. One of the best ways for me to visualize is to create a vision board. I have a big one for long term goals in my bedroom and a small one on my fridge with short term goals. Thanks for sharing you always get my mind thinking and stratagizing. Below is an example of a vision board.
