As far as getting famous is concerned, as soon as you get a bit of fame, monetize your fame and keep hustling to get more fame while monetizing the fame, on an ongoing basis. Because, not all famous people are making money. But, if you are famous, then people follow you and one needs to effectively monetize such following.
In other words, if becoming famous is strategized by monetization, then it is good, otherwise it is useless.
To play it safe, buy a trained pet and train it further and create a YouTube channel dedicated to the pet and grow the YouTube channel, so that the pet becomes famous and monetize the YouTube channel, on an ongoing basis. Yes, there people doing this and making lots of money.
In other words, to play it safe, use OPF (other person's fame) in order to make money. In this case, the other person would be the pet.
