As far as just the writing goes, when I decided to focus on my writing career and make a professional living at it, it took a good two years of daily writing and submissions to any and everywhere to start to see an income, and only then my writing itself only brought in two hundred a month.
It takes time, consistently and patience. No great thing was built overnight :) But if you want it and you build it they will come :)
Awesome advise. I need more positive people like you in my life.
I'm happy to be of help :)
