John petrucci is not a god. And instrucional videos always make you follow a "standard" on your playing, that belongs to the guitar player that you've learned the chops. The best way to learn how to play the guitar is...PLAYING THE GUITAR. Listening a lot of music is the good way to play all these things withou the need of a instrucional video. I have a friend that pick faster like Petrucci, and he never have watched the Rock Discipline. And believe, you'll spend more time watching the video, than you spend playing the guitar.
