I try to tell people this but it just sounds arrogant. These days, though, I am too old to care how it sounds. To think like I do and to know what I know, you have to read at least 10,000 books or book equivalents. I suspect that’s probably the bare minimum if you’re already naturally very smart; most people will require far more.
Truly I have no idea how many books I’ve read in my life, or words. Probably 20,000 books or so if I had to guess. Could be as many as 30,000. For many years I read a few books a day nearly every day. My record was when I was 13 and I read seven books in a single 24-hour period. I was going for eight but I fell asleep. Typically I’d read 20-25 books in a week and I did this for roughly 12 years. My pace decreased after that and then I started reading more online, but I try to stay away from garbage (mostly), so I still think that is mostly valuable reading.
This is the only way to be able to think as broadly and as quickly as I generally do. I followed this path mostly by accident but it’s the only way to not be a dunce.
Humans have inferior hardware, so it takes a lot to get it to work reasonably well. The above is one way to do so.
