Some words are not worth saying. Phrases, too.

• You’re wrong.
• I told you, so.
• Just (in the sense of being the only thing, not in the moral sense).
• Stupid.
• Honestly (as a preface).

Obviously there’s a slew of more offensive words. They’re not worth saying, either.

But the ones listed above?

They’ll ruin your credibility almost as fast.
