There is always work involved in getting passive income set up. I think that's the part some people don't realize. They think money is just going to start rolling in.

Writing on Medium is a decent option, but it takes a lot of work to get it started.

Investing in dividend paying stocks or mutual funds is how most people get started, but you have to consistently invest as it takes a lot of investment funds to make enough in dividends to really supplement your income.

And still others buy a rental property. I've seen A LOT of young people but their first home and rent out the spare rooms which many times pays their full mortgage payment. It's a great way to get started with passive income.

Some people start little Etsy businesses.

There are many ways to make money, but they definitely require work to get them up and running. Once you've got them going, however, you'll be so glad you did!
