2/ If you read any of his books or the books written about him, you'll see he had an amazing capacity to challenge not only conventional views and beliefs, but also his own as well. As I've mentioned in other threads, that's a really hard habit to acquire.

3/ One reason why it's so hard is that our brain's have some funny kinks that exist to give us a "kinder and gentler" view of reality and ourselves than is warranted. One such kink is the foundation of hindsight bias, where our brain rewires our "memories" to make them consistent

4/ with current conditions. And the sneaky part is, we genuinely believe that our current "memory" of what we thought in the past is accurate. One way to see just how true this is is to keep a handwritten journal of decisions and beliefs throughout time.

5/ If you can consistently record thoughts, decisions and beliefs over time, you'll quickly see that we are all "unreliable narrators." An unreliable narrator is a "narrator whose credibility has been seriously compromised.
