When the referee is present to blow the whistle, it’s time to worry about the rules. In the meantime, just write, and do it quickly.

The punctuation officials can’t always agree on the right call. What one style book says is wrong is preferred in another. Different publishers follow their own rules. There are so many guidelines, rules, and exceptions, no one can remember all of them all the time, so what you see in print isn’t a perfect guide. Just know the marks, what they do, and why they are important, and you’ve earned the right to play.

Punctuation marks are important to readers only when they affect the clarity of the message, and that should be your topmost concern. As you listen to the words, hear the rise and fall of tone, the pauses and stops. If you learn to punctuate by the way you talk, considering natural pauses and stressed words, you won’t have to worry so much about rule violations.
