NO definitely not, even now it's somewhat of a side gig. I would gladly make it into a full-time profession if I could. But mostly I write for the joy of it, even though that joy can sometimes be a major pain in the butt.
All the time. I really haven't discovered the best way to overcome it. Normally I just write what comes to my head and if I get stuck take a step back even if that means taking a day or two off of writing. I would say try to destress but just knowing that you have writer's block is a stress in and of itself.
I've always loved to read and be immersed into another world. When I was younger I had a dream about my first book ending and decided to take a chance and write.
