You don't think you would be a little happier knowing that when you die your name will still be written in history books for decades or centuries to come?
No, I don't think so. That doesn't seem to fall into any of the categories of things that have made me happy. I've accomplished a few things that I think "should" make me happy, but for whatever reason I don't feel any lasting difference as a result. Most things that have made me happier either gave me pleasure directly, or were the negation of something that was causing me stress.
