Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.
Hardy struggled to find space at the hospitals to conduct his procedures. Due to this difficulty, Hardy considered opening his own surgery center. He purchased land and developed plans to build this surgery center; however, before construction started, MBJ representatives approached Hardy to ask him about becoming a member. Mr. Hardy concluded that becoming a member/manager of an established surgery center was a better business decision than building his own surgery center due to the cost of construction, staffing, certifying, and operating the center.
The reason I prefer e-books is, with e-books you write the book once and make money forever without worrying about print or inventory. At the moment, I have 3 e-books selling on this blog and the process to get any of them is simply automated. Once anyone makes a purchase, they get delivery within minutes. So I could sleep or spend the whole day at the beach and I would still be making money. Passive income!
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so.

It may be a little less passive up front, but over time you could take your hands off the wheel.
