Professional Blogger
The best thing about Blogging is that you can start off slow, in your spare time and eventually build your blog to six or seven figures.
The most successful pro bloggers will write and publish content in one specific niche, such as travel, parenting tips, cooking, or technology, for example.
The really neat part about being a professional blogger is that there's very little investment required to get started - you need a computer, an internet connection, a website (free or paid) and the ability to write in a way that engages people.
You can also run this type of business from anywhere in the world, which is exactly what many "digital nomads" do.
Your earning potential as a blogger is almost unlimited, but it does take time to build your audience and your income. With that being said, the most prolific professional bloggers earn anywhere from US$10,000 to US$100,000 per month.
