I've missed more than 9000 shots in my career. I've lost almost 300 games. 26 times, I've been trusted to take the game winning shot and missed. I've failed over and over and over again in my life. And that is why I succeed.
I didn't need to write historical epics, no, or science fiction, though I read a lot of science fiction as a kid and rather liked it. But I didn't have the mentality.
You write because you don't talk very well, and maybe one of the reasons that I was determined to write was that I wasn't an orator, unlike my mother and my grandfather, who both spoke beautifully and spoke all the time. Maybe I grew up with too many voices around me, as a matter of fact.
In a democracy in the 20th and 21st century, if you can't base your fiction upon ordinary people and the issues that engage them, then you are reduced to writing about spectacular unreal people. You know, James Bond or something, and you cook up adventures.
