Writing is thinking on paper. Anyone who thinks clearly should be able to write clearly-about any subject at all.
William ZinsserIf you would like to write better than everybody else, you have to want to write better than everybody else. You must take an obsessive pride in the smallest details of your craft. And you must be willing to defend what you've written against the various middlemen - editors, agents and publishers - whose sights may be different from yours, whose standards not so high.
William ZinsserI almost always urge people to write in the first person. ... Writing is an act of ego and you might as well admit it.
