It’s neat to hear how other freelance writers are making it. I can see the struggles you are having based on the type of writing you do. The constant pitching to editors in hopes of getting a piece accepted and then waiting months for payment is hard.
For me, I do blog writing and it’s a great way to make a living as a freelance writer. You deal with clients, you write content and they pay you within the week. I also ghostwrite for big influencers and it’s awesome to see my business growing.
Good luck on your other interests!
