I was just thinking today about how much available time I've had since I had shoulder surgery. A lot. And how much writing have I done? Not as much as I'd have liked to have done. Oh, I've done some articles for examiner.com, and that's pretty much it. Personally, I need to get back into the daily habit of writing, especially if I want to sell anything, especially my novels. I've found that nothing happens without persistence. Well, I take that back, nothing happens without persistence unless chance takes a wild hand in things and luck happens. Since I don't believe luck can be counted on, there's only one thing that can--my own hard work and dogged determination.
That's the key to success in any worthwhile endeavor.
