Is a happy, successful life invalidated due to a lack of self-knowledge?
Or is an overly self-aware person's life invalidated due to their lack of success/happiness?
Many people think they are better than average, think they have more control over their lives than they do, and believe their life has meaning despite no real evidence to support this belief (in fact, sometimes the evidence strongly contradicts this belief). When they make a mistake, they forget about it, and when they succeed they identify with it (even when they fail far more than they succeed).
They go through their whole lives without questioning whether they have built their entire life on an imaginary foundation. They seem to believe anything, except reasonable arguments that might burst their bubble. I'm not saying these people are always wrong, I'm saying that even when they're right, it's pure dumb luck, since it's not like they really thought about it.
These people seem pretty happy to me. Obviously, they have struggles like anyone else, I just mean that their utter lack of awareness doesn't seem to hold them back at all. In fact, a lot of them seem happier/more successful than the people I know who strive for truth.
Is it so bad to delude yourself in little ways, if it allows you to function happily/effectively?
