John Podhoretz

The historical novelist has to consider what has actually happened, while the SF writer is dealing in possibilities, but they are both in the business of imagining a world unlike our own and yet connected to it.

If we live a self-directed, self-motivated, self-centered life, always needing to get our own way, then we're going to be miserable. In fact, many times we believe it's our problems that are making us unhappy when, in reality, it's because we're focused on ourselves!
