Frank, do you have another job that pays your bills? I know that's a really personal question, but as long as you can keep writing while you're working and getting your bills paid, stop and ask yourself why you write in the first place. Is it just for the money? Or do you love to write? is getting paid to write an added bonus to the bliss of creating amazing worlds and characters, or is it your focus? Getting caught up in sales destroys the passion to write, especially if your sales are on the low side, and sometimes it's hard to keep your focus on the passion of writing if you're all wrapped up in how many books your selling.
