Starting a podcast, like making a YouTube channel or blog, comes down to telling interesting stories and building an engaged audience. I’m probably sounding like a broken record by now, but you need a niche that you’re interested in and there’s already a demand for.

The fundamental skills that are required to do a good job take years to hone. This isn’t something you start and are good at over night. And if it takes years of work to get good at, and hours or days of work to arrive at a good product you should not be selling it for $5.

If you have a propensity for writing and you can slay with your prose, consider writing an ebook. While the market has certainly become saturated as of late, books that help teach people about a technical topic still sell extremely well. This is a great source of passive income but does require a large amount of effort at the outset before any money is generated.
