That's not practical advice. Especially in the workplace, you have plenty to say. It may not progress humankind, but you definitely need to say it. You may be discussing a design decision, announcing a promotion, negotiating a contract, etc. In these cases, one might get better at writing and say the same thing more effectively. This is where a person would need practical advice to improve his writing style. I've run into plenty of people in professional settings who would be more effective in their jobs if they could write better. They often don't realize it themselves until a colleague suggests revisions. I read Strunk & White at some point. It has its contradictions, sure, but much of its advice is good if you treat it as advice, and not a rulebook. For example, you might occasionally need the use the passive voice, but it's very good advice to strongly prefer the active voice and to use the passive only when you really need to. Some people really do have a problem using way too many passive verbs, but few realize it until they try writing with active verbs.
