By no means "fun." These kinds of mental gymnastics probably produce a very significant percentage of global human personal misery. And how to know the reality? Well, in my case I did indeed "know the reality," but I kept it in a sealed lead box in a safe in the dungeons of my mind and kept that knowledge from my conscious mind until now. I assure you that "reality" is by no means hard to know. On the contrary, it's hard to cover up, but that can be done and was done by me for my entire life. I'm sure this is a common situation.
