I actually just read this book due to you, aaronsw. Your post on LessWrong where you mentioned it caused me to go out and read it.

I am now aware that ~90% of the people I associate with are very much in the "fixed mindset". It is kind of sad, honestly, because they are all bright people, but you can tell they have essentially stagnated because of their mindset. This includes myself, of course, but I have been slowly realizing the usefulness of the "growth mindset" over the last several years. Now I have a name for it.

Thanks for this. I will be sending your write-up to several of them.
