Ableton's 'Making Music' is very good too...

Heavily focussed on DAWs, but the principles generally translate well and aim to tackle the really difficult points in our music making journeys!

Personally I am a huge fan of 'breaking it all down and starting again', fast and often, picking one, two or even three patch points that I absolutely must NOT use - sub/consciously that can be as excruciatingly difficult or as easy as you want to make it ;)
