You need to decide which machines you want to run, get the necessary licenses to operate them (you're selling items so you need to get sales licenses and whatnot from your state), buy the machines and a truck for the items in the machines, find a supplier of the products, and then finally you can secure locations. Finally, you need to service them periodically or hire someone to service them.
There are now two ways to sell on Etsy–physical and digital products. With physical products, you can either create something unique such as jewelry or buy and resell something–for example, vintage clothing. Etsy has been a great marketplace for a long time, helping creative people sell their goods. The problem is, selling physical products isn’t exactly passive income.
What I Do: I’ve set up multiple investment accounts outside my main operations bank that deals with working capital e.g checking, paying bills. By transferring my money to a couple brokerage accounts and two other banks as soon as it hits my main bank I no longer have temptation to spend on frivolous things. As a result, I can wake up 10 years later and reap the rewards of compounding. My 401(k) is the best example where constant contributions over 18 years has grown to over $500,000 without any savings pain given it just became a part of life. Real estate is also a fantastic asset class for the long term. It’s fantastic to enjoy your home, pay down your mortgage each month, and end up with a paid off asset that has likely appreciated during your time of ownership. 
Online courses have exploded in the past five years. Experts and creators can now create video courses to teach others their craft. A course can be about anything that people want to learn. Friends of mine have created courses and say the amount of effort is similar to writing a book. But once its done and starts to sell, it’s a solid passive income stream.

A truly viral product emerged from targeting a truly viral problem in the digital age, known as attention deficit disorder. Allowing people globally to channel their nervousness into an entertaining handheld device has allowed for the viral spread of Fidget Spinners. The products modest beginnings spread virally through school children and later through to adults. We started seeing fidget spinners in social media, memes with fidget spinners, fidget spinners distracting people while crossing the street, and of course, fidget spinners in the impulse purchase section of your local supermarket. This little product achieved a viral marketing status through providing a ‘solution’ to a viral problem and bringing about a world full of fidgetty temptation.
