Yeah, that dude has created something special on the internet. The sheer
number of hours on camera as well as his print materials blows my mind. He
also appears to be the nicest person on the planet.
It's an odd thing giving advice from the perch of mastery. Justin emphasizes
the "key" is transcribing songs. Similarly, as a go/baduk acolyte, I'm told by
dan players to study tesuji, but most of my practice is playing actual games,
just as it is playing actual songs.
Masters fall into the trap of thinking well, what would I do to get better?
Because of their own preternatural talent and a 360 view of the
discipline, they don't quite see that the less talented, casual learner needs
practice to be a non-chore to stay motivated.
Go slow and steady, practice daily. Follow justin guitar or pebber brown, sit back and practice over and over again.
