You gotta write for the love of writing, every other motivator is a short term quick fix that leads to burnout. That robust writing habit is what will see you turn a profit in the long run (but it is very much the long run). Keep at it, and keep interacting with others. There's a community out there and an audience for everyone - even if it doesn't feel like it for the first few months. You got this. I believe in you. :o)
