C.S. Lewis is smart.

"All human beings pass away. Do not let your happiness depend on something you may lose. If love is to be a blessing, not a misery, it must be for the only Beloved who will never pass away... There is no safe investment. To love at all is to be vulnerable. Love anything, and your heart will certainly be wrung and possibly broken. If you want to make sure of keeping it intact, you must give your heart to no one, not even to an animal... The alternative to tragedy, or at least to the risk of tragedy, is damnation. The only place outside Heaven where you can be perfectly safe from all the dangers and perturbations of love is Hell."
