Some people believe that intellectual ability is purely genetic or fixed.
This is a myth. Research now shows that your brain is like a muscle; the more you apply it and struggle, the more it grows. People who learn to recognize this fact about their own brain develop a ‘growth mindset’ and are able to persevere and achieve more.
At Khan Academy we know abilities are not set in stone because we see people improving radically every day. That’s why today we’re embarking on a mission to help the world realize that if you work hard and embrace struggle, you can learn anything: www.khanacademy.org/youcanlearnanything
