Tweets can be deleted. They can be immortalised. They can ruin a career or make one. They can send chills down your spine or give you insight in ways a whole book might not be able to. The same goes for sentences. They both can be taken out of context. They do not tell the whole story, but they are structures that build something bigger than themselves. If they are flawed, the whole rest of what they constitute can fall apart.
Lately, I find myself reading books scouring them for good ones. Ones that stand alone. Lionel Shriver is a particularly good sentence writer. Her good sentences add up to sensational books.
Sentences are the bones of paragraphs and essays and the joints that build plot lines. I may never get past them. The sentence is as far I can see. I write a sentence. I write another one. I will write another one after that. I will go from there.
