The purpose of this article is to help people decide which brain power products are best for them. I'll provide a short summary of all brain power products and a detailed comparison for each product. If you want to learn more about a particular product, you can always visit my website, where I've uploaded a large, thorough list of brain power products that I have used over the years. Also, if you are looking for a specific brand, you can simply click on its name or the name of a popular brand on the left side of this page. I've done this to make this article as simple as possible. When I first started learning how to improve my mental performance, I was so overwhelmed by my problems that I thought that all I needed to do was to simply focus on the most critical areas. My teacher, a psychologist by training, told me to focus on the problem areas that were most important to me, even though I could not see them, and I would be much more successful in achieving my goals. The problem with this approach is that I soon realized that I could do more good in the areas where I could actually see the problems and change them to be more beneficial, such as reading and working on writing. However, the more areas I focused on, the more problems I found.
