From NPR’s Student’s View of Intelligence Can Help Grades:

The students in the latter group "learned that the brain actually
forms new connections every time you learn something new, and that over
time, this makes you smarter."

…

By the end of the semester, the group of kids who had been
taught that the brain can grow smarter, had significantly better math
grades than the other group.

You can get smarter.  So pass it on!
