Do you think freelance writing is a side hustle?

In an article on Bankrate, freelance writing was suggested as one of ten side hustles. To me, side hustles are things anyone can do to make quick mone, although Merriam-Webster defines it as "work performed for income supplementary to one's primary job." That's not necessarily saying it has to be quick, but most people who are looking for extra income do want it sooner rather than later. That's not what comes to mind for me when it comes to freelance writing 

Practically anyone can learn the technicalties of writing. They can learn what works and what doesn't, but that can take quite a bit of time. And if you're starting from scratch, it's going to take a lot longer to build freelance writing into a side hustle than it would being a shopper or working with a food delivery service.  

It has taken most of us writers years to get to the point where we're making income, and even then, many writers don't make that much money a month, especially not enough that it could be considered a hustle. 

Freelance writing is hard work, and it involves more than writing. You have to learn the process if you're not a writer at first. Then you to learn how to find publishers looking for what you're interested in writing. You have to learn how to craft a query letter, how to submit a pitch, and how to make a topic an easy read for the market. 

Overall, I would never consider freelance writing a side hustle. It can be a part-time or full-time job, but iyou're not going to make a lot of money fast from it, and you're going to have to invest your own money to learn and to grow as well as to market your own work. So if you're looking to make quick money, you won't find it by freelance writing.
