This is a much better article than the one from Gates. Thanks.
The "Growth mindset!" safe word part at the end was quite apt.
However, it's possible to get a LOT done when you're not growing. For example in basketball, if you know how to do a play which beats other teams all the time, then running that play can be a great idea. Of course, perhaps another team finally figures out your plays and they become useless. Then you might wish you'd spent some of that time growing and developing more plays.
Like how Gates is successful, and is able to spend more of his time growing and trying different things. Because he doesn't need to spend a lot of his time executing successful plays so he can pay rent.
Thanks for the link. As someone who's never heard of Dweck, I learned a lot from Aaron's point of view on the topic. Also Gates is totally right when he says that this isn't black and white. I'm growth mindset about some parts of my life and embarrassingly fixed mindset about others.
