An exercise in life coaching: write a letter to yourself in which your dreams have been fulfilled at some point in the future.
It was often hard getting started in the beginning. Struture to a day is most likely required even if one doesn't particularly want it. Sleeping days away at a time without a single word from the pen can't exactly accelerate your career. But you overcame that, eventually.
A schedule - the very thing you despised, became a godsend to your work. Write for a while in the morning, research on location or online, pick the kids up from school, and then go home to work some more while they do homework. Oh, you didn't realize? You don't work at the courthouse any longer - you survive strictly on writing and photography.
Of course you worry - there are up times and bad times. But every single rejection can never dim the excitement of receiving the acceptance. Just remember that.
You house has been redone to suit you - wood floors throughout and cabinets and a proper office, filled with bookcases. No more dining table or kitchen bar for you!
Congrats, my girl. You made it!!
