It's too bad I can't really recommend "Have your life ruined" as a cure for worrying, because it works like a charm. Not only do big, real problems put little, hypothetical ones out of your mind toute de suite, they also give you a chance to prove to yourself, in your handling of them, that you might possess enough wits, resources, badass characteristics, or simply patience with situations that truly suck ass, to actually handle most problems big or small, and know that you'll be pretty much okay no matter what happens.

Some people worry because of things they've been through, but if you're the type who worries about things you've never been through and will probably never go through, going through some actual shit will put an end to that. It worked for me. A several-year period that included the deaths of loved ones, long-term unemployment, divorce, etc., made me start focusing on what's important and, more to the point for your question, completely stop worrying about stuff that's not important. It sucked though, and it's really not the sort of thing you can plan, per se. But I came out of it and now it's like, yeah go ahead and try to threaten me... I'm not scared of anything after all that!
