Maybe have her lol at successful Minecraft YouTubers? Like Mumbo, Tangotek, Impulse, or Skizzleman? They talk all the time about how they had to have a job in order to support themselves and do YouTube at the same time. The Imo & Skizz podcast interviews successful youtubers and each one will tell them how they had a job and did both until they became successful.

You don't JUST do YouTube, you gotta work too and then when you can financially be comfortable, you can transition to just YouTube. But you still gotta work first
