"What I liked is that everything is backed by science"

You don't need a paper and pen, but you will write a lot of the things he's saying out of sheer will. Pure gold. As Jim is saying, first thing to master is your mind and the ability to learn and evolve faster. He's touching all the aspects of learning and self-development, giving practical, easy to apply tools in all the areas, while focusing of course on the brain's ability to store and retrieve any type of information you want to, Fast and Easy. Also, what I liked is that everything is backed by science, so no need to question his facts / no way you can find he's not right, at least from the reliable sources out there. Here you go, one more person saying that you should definitely do this. If you have even one minute to spare today, spare it now on starting this, you won't regret.
