When I think about fame, I think about something Chloe Sevigny said. She was dating Jarvis Cocker and she said they could not go anywhere without mobs of people being after them and that made her decide she did not want that level of fame, so in a lot of ways, it can be a choice. She said it dictated a lot of her working choices after that. She's worked steadily since the 90s so I guess it can be done.
You are reminded of them by the I do everything Moz does? Unfortunately, there are too many people like that, it just shows a real lack of a personality or core. I get that people are unwell and sometimes can't help it, but for some it becomes a crutch, you have to be willing to try to help yourself.
