I'll skip the clutter. The key to happiness is limits. Whether self-imposed or imposed upon you by an authority figure, being limited in what you are able to do is the reason we get so much joy when we are actually able to do those things.

If you are given free reign over what you can or can't do, you will soon find the things you are able to do so much of have lost their appeal.

So if you want to be happy, either muster up some self-control and impose limits upon yourself, or get someone to do it for you. I guarantee you will be happy.
