Wow, a wonderful technique

I'd never been interested in Stoicism, but I recently came across this:

If you're fond of a jug, say, 'This is a jug that I'm fond of,' an then, if it gets broken, you won't be upset. If you kiss your child or your wife, say to yourself that it is a human being that you're kissing; and then, if one of them should die, you won't be upsetting.
                                   Epictetus

And it seems to work even when it comes to kissing yourself.
