I would adjust the tone for the "I am in Arts" section. Saying "I think you have math issues" is not the kind of welcome you want to give to people who do, in fact, have math issues.

I like the end, where you emphasize that math is a great exercise in abstract thinking and modeling. But I would start with something more neutral saying something like, "Many people had suboptimal experiences with math in school because it was often presented well, and some teaching styles don't work for some people. And some may have just always found other things more interesting. However, my goal with this book was to make math more accessible and interesting to many people by presenting material in more a more intuitive manner and emphasizing the core skills of abstract thinking and mathematical modeling of the real world."

That's definitely not perfect, but it's something to start with. Try to imagine that you're someone who never found math all that interesting and always thought that literature or history or art was far more interesting and meaningful, and that possibly you had some bad experiences with math and got the idea that you're not good at it. Now try to imagine what might trigger those bad feelings about math and turn you off to a book, versus what might make you decide to give it a chance. If you don't trust your ability to imagine this way, try to find a close friend who is in this situation and will be honest with you.
