Zig Ziglar

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.

When you feel the need to moan and groan, laugh with woeful recognition and eat flaky pastries. If you hear yourself taking the art of complaining a little too seriously, ask yourself what you're trying to accomplish, exactly.
