"Growth vs "Fixed" Minds

This was a podcast done from a Stanford University psychologist. This was a great podcast. I think people are really like that. You know you set your mind to something and you can do that something, but some people set their minds that they aren't going to do something and they end up not doing it.
I think it was amazing how the students had no clue they were in the program, but the teachers knew exactly by the way they acted and how there minds were.

In one point it made which struck me as surprising at first was that people with a fixed mindset often have had lots of praise. It makes the point that just telling your child they are clever, or wonderful, or whatever, sets up a belief system in them which can become fixed and she recommends instead praising children for their effort, for what they’ve learned. This is a key point really - that when you have a mindset about loving learning you can grow, but when you have a mindset where you think talents are fixed then you get stuck.

If this is what will help out students then why are we not all doing this.
