Hai Khushi,

To become a freelance writer, you have to first of all understand your skill/area of interest. You can start blogging on topics you are interested in. You can build network of freelance community. Make more work and even make your own platform for this.

You may start writing articles for different publications. All you have to know is that if anything you have to earn depends solely on your work. So you have to keep improving your skills as you write.
