When I wanted to learn set theory in high school, I found Halmos Naive Set Theory book very readable and understandable. But now, at university, I have been searching for a similar book in category theory, but I haven't found any book like that until now.
What is your suggestion?
Thanks in advance.

Right; at college level, before, especially, algebraic topology, you are probably best off with something like SPIVAK. Also available as a pdf is Mac Lane, written by one of those who invented category theory, as something of an outgrowth of homological algebra. The latter is probably intended for graduate students. Meanwhile, it would not be surprising if there were still other books, at various levels. Category theory has become indispensable for, say, algebraic geometry.
