SAPIENS: A BRIEF HISTORY OF HUMANKIND by Yuval Noah Harari

I started Sapiens because it was the #1 most recommended book in Tools of Titans, which sums up the recommendations from top performers in many different areas. The reviews are amazing too, so I could not go wrong.

Sapiens is not the most fun book to read, because it refers a lot to historical events, but this is great knowledge to acquire or revisit. I wasn't amazed during the first pages and even considered stopping reading it. Happy I didn't!

The main insight I got from the book is the number of things that we think are objective truth are actually inter-subjective, meaning they are taken for granted because most people take them for granted, but they rely only on this trust. A few examples would be the way we eat or money.

In the case of the way we eat, it talks about how we don't question the treatment of animals in our Western societies, the same as people used to not question slavery. As a consequence, I started having vegan meals most of the time. In the case of money, it made me realise our money system was only based on the common belief that the dollar was worth something, but the moment we stop believing in it, we'll realise it has no intrinsic value. This led me to move more savings to cryptocurrencies, that are better optimised.

I sometimes refer to Sapiens as "LSD in a book", because it makes you challenge all your beliefs that you had taken for granted and really opens your mind to the fact that the reality you know is actually subjective. It gets you out of your own head and your comfort zone. I've since then talked to a few people who have read Sapiens and the book in itself creates a community of open-minded people with whom I love to discuss.

And after reading Sapiens, you can tackle Homo Deus, which I found maybe even more amazing! Ready to take the red pill?

But don't trust me, trust Barack Obama:
