There is a simple and obvious solution to this "abundance boredom": remove the abundance. There. Done. Put all your money in charity or, if that's too altruistic of you, lock it away in investments where you can't get at it easily and force yourself to live off of the national median income (~$38k individual, $70k household in the us).

The thing about being poorer is that you can't do the opposite, so it is quite understandable that no one in a poorer position has any sympathy.
