its called capitalism

capital= money

no money = no capitalism

Only fans. That’s literally your only option. exploitation.
Because someone else (your pimp, aka the owner of OF) gets a cut of your income.

Imho the easiest way is to find a skill that you can learn, ideally at a school, that’s hard to learn and is stable. Then you can go into business for yourself selling that to others. Skills like accounting, home nursing, tutoring, medical care, financial advisor, IT, database maintenance, plumber, electrician, elder care, handyman. Not all of these pay super well, but they let you start your own business.

How many guys can you jerk off in 8 hours?

You dont. Unless you can get some loans you’re gonna have to either find a way to do it with no money (usually extremely specific circumstances) or not do it. I pumped about 5k into a computer repair business that never got off the ground and I am still down from that 2 years ago.

You need more of a plan than “I hate my job, I want to start a business.”

You don’t even say what kind of business. House painting? Landscaping? Financial consultancy? Church?

How would running the whole business be better than working for someone else? How would it be worse?

No money? There are some knowledge worker consultant-type businesses you might be able to start with no capital but you either need a bunch of money to sustain you through the early months/years or have another income.

Without a clear goal and plan you’re better off keeping your job and doing stuff on the side and see how that goes.

You buy low and sell high. But buying low requires money. So here’s how you do it:

Your labor power is yours. It has a cost to reproduce: sleep, food, shelter, clothing, medicine.

1. You can trade your labor power for more than it costs to reproduce. That could be a job, or it could be gig work. But the critical thing is the price, and that means you have to be very good at selling.

2. Somebody out there (Amy) has more money than they know what to do with. Somebody else (Beau) has something they need to sell. A third person (Charlie) wants to buy the thing Beau wants to sell but Charlie is not aware of Beau. You can go to Charlie and offer to sell them the thing for more than Beau is selling it for. If they agree, you go Beau and ask Beau to lend you the money and in exchange you’ll give Beau a portion of the profits. The critical thing is the price, because you still have to reproduce your labor to do this, and since price is critical, you have to be really good at sales.

There might be other ways.

Save up first

Then start a business?

Mow lawns.
