I would suggest reading through and practicing some of the snippets as you go along (however, I would _not_ suggest doing the little projects, often they can get you sidetracked). By snippets I mean things like `foo.chars().iter()` and such to understand exactly what's going on underneath the hood when you use (for example) a `.chars()` or a `.iter()`.
But the book will only go so far. To take things further (especially with Rust), I suggest "reading code". There's plenty of it on Github. And I would definitely add that Rust devs in particular are usually better than most at commenting code (which helps).
