I think the "Growth Mindset" thing is one of the best things Satya did. I joined Microsoft as a hater of pretty much everything Microsoft. I use a Mac as my daily driver and Linux servers for all my work stuff. I lived through the Balmer era as a VERY critical outside observer. So, I went into NEO (new employee orientation) very skeptical. The way they (under the growth mindset mantra) admitted to their past failings and hubris that lead them to do things like assume their way was the "right way" and underestimate their opponents (namely Apple). Hearing them speak transparently about that and how they now have a culture of admitting when you might be wrong was refreshing and exciting.

I do not currently work at Microsoft, but was there for a few years and enjoyed my time there.
