Yes, we talk like we think, and we think like we talk. Our minds and our mouths are inseparable.
Also, how we talk to our children affects how they think about themselves. Listen for how many times you say “perfect” in a day or a week. There is no such thing as “perfect” so setting that as a goal guarantees failure.
Try removing that word from your talk for the next few days. Instead aim for excellence both for yourself and your children. “That was excellent, outstanding, superior, awesome.” Aim for personal best. “That was better than I’ve (or you’ve) ever done it before.”
Track how successful you are avoiding the word. If it seems hard, keep trying. If you’re making progress, keep at it until it becomes a habit. Some experts on habit formation suggest the first 3 days are the hardest but at 3 weeks it begins to feel more normal.
