I thought you were joking but look at your replies to everyone's opinion at the first page... yeah you at least put some thought into that. Start today but rake in profit right at tomorrow doesnt seem like it was possible for any legitimate business. You could do it at the small scale, niche or something but any more than that, huge revenue then it becomes a headache. For example, a lemonade stand. It requires little in preparing while you can rake in profit right away. But of course, we all knew that it was just for chump money, just 1 stand and a little kid thanks to people found it amusing. You couldn't make it to become your main fishing pole.
Or maybe open up an onlyfan account. Nerds and simps will throw the money at you right away as long as you're a 10/10 stacy. But I don't think people want to go that route since you know, society still frown upon it. Talk about e-girls business, I remember there were a lot of orgs that lording over those e-girls, acting as their management or training them, taking a cut from those girls.
