“I wish, my dear Lucilius, that you would not be too particular with regard to words and their arrangement; I have greater matters than these to commend to your care. You should seek what to write, rather than how to write it – and even that not for the purpose of writing but of feeling it, that you may thus make what you have felt more your own and, as it were, set a seal on it. Whenever you notice a style that is too careful and too polished, you may be sure that the mind also is no less absorbed in petty things. The really great man speaks informally and easily; whatever he says, he speaks with assurance rather than with pains.”

For me, this means getting past that sentence that sounds awkward and just keep writing. If I want to convey how I feel about a particular theme, no amount of editing, polishing, or touching up will help me get to that point. Feeling is often messy, so too its conveyance.
