She reminds me of most single women I know who have careers like "event planning" or "social media coordinator".
They're uniformally obsessed with traveling and it's very common for them to travel alone, to "mad respect" from their friends on social media. They also love food and fancy varieties of hot tea. They all have Instagrams that are dominated by selfies and pictures of plates of food. Going by their social media posts, they seem to be living dream lives, but they're also usually fairly vapid people.
They don't read anything (except maybe Harry Potter novels). They' don't produce anything. They'll travel three or four times a year all over the world, but they don't ever come back as smarter or more interesting for the experience. They just saw some sights and ate some food and don't have anything to say about it except maybe "The pho is so much better in Vietnam".
They're just filling voids, with no real passions or interests or real responsibilities to keep them going when/if sharing pictures of their lunch stops being fulfilling.
My biggest surprise in the story above is that this woman turned that corner fairly young. Didn't even get to 30.
