One of the sources of what to read is the book-list of people that are light years ahead of me, like Charlie Munger, the billionaire. I’ve read science books because of his book list. Other ideas come from my own articles: like reading Sarah Singer and Blair Singer, whose books and videos are setting my world on fire right now.
Believe it or not, I spend the bulk of my time studying, reading, watching videos, testing, and writing articles. About 3-4 hours a week on eating, preparing stuff, hygiene, and food shopping. etc. and the rest on business per se.
The biggest challenge I have is to remember to generate income.
