Picture your inner voice as a coworker. Would HR have a file on them by now?

Speech you would never accept from another person often runs unchallenged inside your own head, mostly because it is familiar enough to sound like plain fact. The test works because you already have a clear sense of what is unacceptable. You simply never apply it inward, where the speaker has no name and the commentary never stops.

Write down one thing you said to yourself today and read it as though a colleague had said it. If it would be a problem from them, it is a problem from you. Rewrite it into something you would say out loud.
