Research shows that parents can have a powerful impact on their child's mindsets. The language you use and the actions you take show your children what you expect. So as parent it seems smart to develop a growth mindset in your child. Teach your kids: "When you make a mistake it’s not an indication that you are doomed to be a failure; it’s an opportunity to grow."
Remember that relationship is connection not perfection. Monitor your self-talk. Pay attention to your own internal dialogue about abilities. When you or your child struggle to do something, do you tend to conclude that you can’t develop the needed ability, or that you haven’t developed it yet? Say positive words.
