The key to good worldbuilding is leaving out most of what you create. You, as the author, had damn well better know the where all that dragon food comes from, but that doesn't mean that I, as a reader, want to read a five thousand word essay about you explaining it to me. I don't need to see the math, but I can tell by the details you provide whether or not you've thought these things through to their logical conclusions.
Patrick RothfussI don't actually have cable. I watch TV, but only shows that I buy on DVD. As a result my TV rage factor is pretty low right now. I do have a real distaste for those extreme makeover shows. I once caught a roommate watching one and proceeded to rant for almost 15 solid minutes about how, in watching that bullshit, she was actively contributing to the destruction of all civilization.
Patrick RothfussRemember this son, if you forget everything else. A poet is a musician who can't sing. Words have to find a man's mind before they can touch his heart. And, some men's minds are woeful small targets. Music touches their hearts directly, no matter how small or stubborn the mind of the man who listens.
