I used to think that when I added stuff to my brain I’d get smarter. But this is not true. For instance, if I look up when Charlemagne was born I’d just add a fact to my head that I will forget tomorrow but will clutter my subconscious mind. This won’t make me smarter. Subtraction, and not addition, is what makes the window to the brain more clear,

In my opinion, one of the most rewarding ways to improve brain health is by learning something new.

I can be smart. But at the moment, I’m largely an idiot. I feel that I have the right knowledge but I let a lot of stuff get in the way. My head fills up too quickly with thoughts.
