Dear Sarge: the best way I know to make money without working is to invest in real estate using other people's money.
This only works if you buy property under value, finance it low, refinance it high, use the new loan to pay off the old one and also collect on the monthly rental where it covers the monthly costs and you still make a profit.
So if you can figure out the math on a property value, you make money borrowing from others to buy property, use the rental income to pay it back and pocket the difference.
If you start now, you can work even a measly job, save up money for your first down payment on a house or loan, and once you buy a property, you use that as leverage to get more loans to buy more properties.
A lot of the wealthy people who retire early use real estate to become financially independent, and hire out the work to other people so they can live off passive income.

I know people who founded and run this network training others to acquire enough properties to retire as millionaires. If you can follow the model, you don't have to join or pay anything. But the math has to work; you cannot buy property that does not allow enough profit margin. You have to price it right for this method to work. [the mentors use the network membership to walk investors through all the research so they don't buy the wrong properties to begin with. The members/founders make their money off their own properties, not off the teaching.]
If you don't have money, you form a team with other people to lend the capital. You run the LLC and are in charge of using this system to buy the right properties, and divide costs/profits with investors who lend you the money.
this is the laziest way I know to retire with minimal work to set it up right, where you can hire the rest out later. It takes 2-5 years for full time investors to acquire up to 10 houses to quit their jobs, and maybe 5-10 years to move up to apartment complexes which are easier to manage through hired staff than multiple houses on your own.
Hope you had a nice nap through this msg! You can wake up now, it's over!
