I just read this article on Copyblogger and it got me thinking. http://www.copyblogger.com/grammar-rules-to-break/
Some people get too caught up with grammar rules. At the end of the day, the point of using words is to communicate ideas. If you can get your point across, people shouldn’t think less of you because you used the passive voice or one too many commas.
I understand the importance of knowing what correct English is. One reason (I believe) I’m a good writer is because I learned a lot about English vocabulary, spelling, grammar, syntax, and punctuation in junior high. But I abandon those rules all the time, especially when I really want to give a persuasive oration. The best part of knowing the rules is knowing when to break them.
It’s like in music. The best improvisors are usually the ones who spent hours as a kid mastering the scales, chords, and other aspects of musical theory. But when it’s time to perform, you need someone who not only knows the rules but is not afraid to throw them out of the window and just jam.
