If you want to write a good sentence, you must learn to love the full stop. Love it above all other punctuation marks, and see it as the goal toward which the words in your sentence adamantly move.
A sentence, once begun, demands its own completion. As pilots say: takeoff is optional, landing is compulsory. A sentence throws a thought into the air and leaves the reader vaguely dissatisfied until that thought has come in to land.
