You can become a better parent/teacher/coach/boss with a growth mindset.
Listen for one day, very carefully, to what you say to your children/students/subordinates.
Remember that every word and action sends a message. What kind of messages do you notice?
Next time your child (or subordinate) messes up, watch and listen to yourself very carefully.
Constructive criticism is feedback that helps. Do not judge or label. Write down the constructive criticism you gave.
