More than that: a growth mindset perfectly fits the biology of the brain work. According to “Increase your mind power” (by Dr. Jill Ammon-Wexler) our brain transforms all the time and our thoughts and beliefs shape it. Your brain always adjusts to make your beliefs real. It doesn’t care if they good or bad, your brain just make it real for you.
I strongly recommend this book or my highlights of this book for reading!
