What is the best way to convert people to the One True Faith?

I converted to traditional Roman Catholicism two years ago after discovering Catholic materials. My parents and family are New-Age pagans at best, and as much as I hate to say it, according to my catechism they all lead very immoral lives. My question relates to the missionary duties of Catholics. What is the best way to convert people? It seems like there are different methods: good example, outright preaching, and so on. If the Jehovah's Witnesses go door to door all the time, aren't they making more of an effort than traditional (i.e. real) Catholics? I don't know whether a good example is enough.
