You need to believe in them.

Virgos are so driven by their insane ideas about how they want to make the lives of the people they know (and the lives of people in general) as good as they can be. To win over a Virgo, you need to be the kind of person who will talk through their irrational fears and then show up at the launch of their new co-working space (or funky Halloween party) or probably both in the same weekend, TBH.
