I started with SICP to understand Lisp conceptually (it also taught me a lot about abstraction). Then I worked through Practical Common Lisp to learn the ecosystem a bit better and programmed some tools for my own tasks. Finally I worked through “Write yourself a Scheme in Haskell” which deepened my understanding and actually ended up with me spending more time with Haskell than with Lisp (it was a gateway drug to more structured functional programming). Overall this sequence was a very satisfying experience and I now find myself spending most of my time with Erlang which feels a bit like middle ground.
