Although maybe taking random HN advice isn't good, I don't think "Understand your own brain and make your own hacks" is necessarily the best route, either. Your brain isn't a special snowflake. It's subject to the same structural issues as everyone else's brains - instincts, cultural biases, education, etc. If you want to understand your own brain, it's very important to study great thinkers on the subject, both modern scientists and thinkers from the past whose insights have survived the test of time. That doesn't mean you need to commit to any one of them (especially when they are often at odds with one another), but their insights are valuable.
