People tend to forget about bad stuff, and remember the good times. It's a brain coping mechanism. This happens even when you've seen a bad movie. Can you recall specific details of any bad movies you saw a few months back?

Conversely, even important positive events are easily forgotten in a matter of days.
As for the piece you linked, MonkWren... that's all good and well, but principle 3 seems foolish. Why? Because happiness and sadness are the driving forces behind what we do. If you can choose to turn off mystery, there no longer is a 'stick' forcing you to do better. If you can choose to be happy whenever you want, there no longer is a 'carrot'.
What this person suggests is to be permanently content with mediocrity. Sure, you'll be happy
if you get his idea to work, but you'll be an entirely self-centered, entirely useless egotist wallowing in how awesome they are. I'll take misery over that any day.
