It’s not that easy I promise , and I’m not saying that to be funny , it’s time consuming , you have to be popping on all platforms , to get that kind of money and trust me the pressure to collab from fans will have you rethinking solo after you see the difference in money from solo vs collaborating.
Also be prepared to have your entire appearance and personality, judged by strangers, some will love you and someone will hate you for no reason!
I have a friend who does OF content and easily brings in 15-20k a month off of solo content.. Today might be the day I go buy me a camera and tripod lol
