Derek Sivers' advice to anyone who writes. Try writing one sentence per line. I've been doing it for 20 years and it improved my writing more than anything else. New sentence, hit enter, new line. HTML or markdown combines separate lines into one paragraph. Why is it so useful? It helps you judge each sentence on its own. Delete any sentence not worthy of its own mind. We need to vary the lengths of our sentences. Sometimes short, sometimes long.
