I cannot recommend reading A Mathematician's Apology enough. It was written by GH Hardy and I think it's one of the best non-math texts out there to understand how a mathematician's brain works.
I also like mathematician's apology and would recommend it for understanding now a mathematician's brain works and in particular a mathematician's perspective and mindset on being a mathematician.
But I'm curious what prompted you to bring that up in this thread? I don't see how it's connected to the blog post.
