A couple of days ago I stumbled upon 「A Mathematician's Lament」, by the mathematician Paul Lockhart, in this thread on lainchan.

I won't write a review on this short book due to sheer laziness, instead, I am just going to leave a quote:

「The difference between math and other arts, such as music and painting, is that our culture does not recognize it as such.」

- Paul Lockhart

I think that if you are at least a little bit interested in math, you should read it too.
