Best wishes on your quest TSJMajesty! I would caution that the "die on that hill" commitment may interfere with you accomplishing other great things musically. Find your limits, find your style and create. I would also say that for something as complex as this, if you are not practicing EVERY day, it will be even more difficult to get there. That said, I also have a rule about not playing the same thing over and over. Speaking with a producer a few years ago who has some impressive accomplishments under his belt, he said he will not let artists play anything more than 3 times in a row when they are tracking (I know, you are practicing/learning, not tracking but still applies IMO to a large extent) because things generally start to deteriorate after that and they come back and revisit it another day or later in the day. I have implemented that in my practices and have found it does me well. I have successfully violated this practice, but try to walk away and revisit later after I have taken a few good shots at it.
