Basic Category Theory is cute, but I think the exercises are sometimes
phrased strangely.  In some ways, the book makes more sense if you've
already seen these ideas once & are trying to get a more CS perspective of
the math.  I'll probably be alone in this, but I think Mac Lane is a
fantastic book for learning category theory.  It's hard, but if you trudge
along and do the exercises you learn quite a bit.  It's fun!
