Re: Forced motivation
Forget about speed... Concentrate on chord building (via intervals) timing and picking technique. Don't get too wrapped up in theory, as you can always go back and learn that later. Experiment with alternate tunings. Shut-off the distortion and train your ears to recognize the pitch of each note without looking at the fretboard. You must learn to recognize tones the same as your eyes recognize color. Familiarize yourself with blues shapes and pentatonic scales, since most great songs contain these. Less is truly more! It's not how many notes you play, but how well you can utilize a few. The cornerstone of developing "your" sound is developing your hand vibrato and phasing... Without these, you're merely going through the motions. Practice playing the notes of vocal lines (melody) to develop a sense of phasing. Peter Frampton and Don Felder are two of the greats when it comes to phasing. Most "metal" players are awful when it comes to phasing IMO. Randy Rhoads, Michael Schenker, George Lynch, Angus Young and Rory Gallagher (to name a few) were/are great at phasing and hand vibrato.
ALWAYS PRACTICE USING A METRONOME AND/OR A BACKING TRACK.
