Some good stuff being shared here. I'll throw my 2c in
METHOD 1
Build a website. Spend $1,000 on content and $1,000 on SEO to rank the website. You have now invested $2,000. But you have ranked the website in Google, so the traffic is free and the money you make from it is pure profit. Wait until you recoup your $2,000 and rise and repeat on another website. Over time you will have 10 websites and $20,000 invested total but unlimited earnings because your websites will earn you passive income.
METHOD 2
Make 10 Instagram accounts. Get 10,000 followers on each. You now have 100,000 followers. Post pictures on each one with a link to an email submit with at least $1 payout. If even 1% of people click and submit their email addresses, you have just made $1,000. Rinse and repeat daily for easy $1,000 or more per day and continue to grow more accounts until you have 1,000,000 followers and $10,000 per day. Make sure to make a journey thread before you attempt this method.
METHOD 3
Look up basic ways to make money online. Pay a writer 1c/word to create a 10,000 word eBook ($10). You have now invested $10. But you can price the eBook at whatever price you want. That's the beauty of owning your own product. Sell the eBook for $97. Since you paid the writer $10 you need to make only one sale to get back all of your investment. After that it is pure profit. Sell at least 10 copies of the eBook each day for another easy $1k/day.
METHOD 4
Post an ad online for overseas workers looking to make money. Tell them to go sketch the fuck out around local car dealerships and harass customers who exit the car dealership. Tell them that if the customer is unhappy, they should say that they know a guy at another car dealership, and ask if the unhappy customer wants his information. Then get the customer's info instead of giving the info to the customer. Get those leads and convert them into car sales. If you hire 10 VAs and each VA gets 5 leads per day, you have 50 leads per day. The average profit on a car purchase is over $1,000. If even one of those leads buys a car per day (2% conversion rate), you are now making a minimum of $1k per day. Rinse and repeat until you have a VA standing outside every car dealership in your country.
