Using the Caps Lock feature on the keyboard would be a sure fire way to ensure that people ignore what you say. You may want to go back to school and give it another shot, and actually make a real attempt this time. You never know, perhaps you might learn how to pay attention to what you have just written and think about it under the context of who is receiving the message instead of just you, who is writing it.

That being said, I wish you the best of luck.
