There are some excellent points in ten things I have learned from writing popular fiction. A few favorites are:
2. It helps if you honestly like to blow stuff up. Or at least write about blowing stuff up.
3. All books are broken. Some are less broken than others. Some are broken in ways that a particular set of readers do not mind in the least. If you can find out the group of people who do not mind the ways in which your books are broken, you have identified your target audience. Unfortunately, this fact does not excuse you from actually learning to write.
7. If you make it too accessible, people will assume it’s not artistic. If you make it too artistic, people will assume it’s not accessible. Go ahead and blow something up if it makes you feel better.
