There is no such thing as “perfect,” “always,” or “never.”
Pay attention to when you use the words perfect, always, or never. When you catch yourself saying these words, stop and think, “really”? Can a person really be perfect? Is there anything that always happens? Can you promise never to do something?
Make a commitment to yourself to erase these words from how you talk. It won’t be easy, but by sticking with it, you can gradually make progress and greatly reduce how often you use these words.
If the children you care about are old enough, share with them that you are trying to not use these words as often and why. Perhaps they can remind you if they hear you use these words.
