Please don't. SICP is beautiful and all, but it's neither an intro nor practical/immediately useful. There's a lot of enlightenments to be had by reading it, but they have very little to do with Racket specifically. IMO, it's a bad book if your purpose is learning Racket.
> You might, as a novice coming to Racket, find "Realm of Racket" to be more approachable
Or, as an experienced programmer, be bored to tears by the slow pacing and didactical style. It's a great intro to programming and to Racket, but more focused on the former, which makes it ill suited for experienced devs who want to learn Racket.
