Your brain works with the info it has
It is an easy experiment that you can try for yourself.
For example, read a book in one day, watch a few seasons from your favourite tv series or dope your brain one day with so much info that you will not have time to think about something else. After that, everything you think is about that subject. Your brain will try to analyse it and empower you to follow that subject closer.
That’s how we can trick our brains into learning new stuff. That’s all about all the nonsense info from books about self-help. Force the brain to absorb the information that interests you.
