I assume I'm below average

Then you (if you are the author of this post) would almost certainly be incorrect or a liar. The majority of American adults read below a sixth grade level, yet you have published multiple books. You are likely aware of this, so I am going with liar.

I believe this lying is probably what you mean when you say in your other writing that you should adopt beliefs that benefit you rather than those that are true. I find this morally reprehensible.

I definitely wasn't a good driver
