Very nice. Also recommended reading is Eugenie Cheng, The Joy of Abstraction[1] which emphasizes diagram chasing to visualize abstract relationships.

Eugenia Cheng is great, but the completely unwarranted political nonsense that fills this particular book is quite disappointing (I don’t seem to be alone; many reviewers concur). Mathematics is much more fun without all that.
