Parents aren't always sure how to most effectively support their kids' development and help them sharpen their brains. The good news is that a lot of good advice can be summed up in a single goal: Help them adopt a growth mindset as often as possible.

When we're in our growth mindset, we believe that our capacity to learn is unlimited. In our fixed mindset, by contrast, we believe that we were either born with certain talents and strengths or we weren't, and there's nothing we can do about it. 

Because we all have both mindsets and move between them based on the situation, the No. 1 way to help kids succeed is to encourage them to access their growth mindset more of the time. Research shows it can dramatically improve their attitude, engagement, and performance.
