Simply put, I thought that the people who think the most would, statistically, be more likely to think about their self-worth, and thus doubt themselves. However, they could, theoretically, solve their self-doubt quickly due to their increased thinking -- instead of thinking about the matter at intermittent times, they would think about it intensely and solve it earlier. So perhaps its an individual thing.
I've recently decided to make a go of the full-time fiction writer thing. I still do the bare minimum of my freelance writing work so my kids don't starve or anything, but the focus is 90% on fiction. I doubt this decision every minute, but I'm dedicated to it none-the-less.
