Buy 2 or 3 really cute puppies, prefer large playful type dogs I like Boxers, and become a vlogger on YT. Document their lives. Set up a site telling people, for free, what food, toys, grooming advice, training they can buy and get sponsored by the makers of the food, toys, groomers, etc.
Hit Facebook, Instagram, Reddit, etc.
You'll make more money, have more fun, less hassle and work less than anything you do in adult.
Other than that by a big tube of lube and be a rent boy.
