in light of

1: {Steve TerryBerry's vid on master-ful guitar players with [unconventional] picking techniques}

I don't really believe in "bad habits" of guitar playing anymore.

you are either {making the sounds you want to make & eliminating the sounds you don't}

or you {aren't}

for a lot of players they just figure that out by playing and noticing what they like about the sounds they're making; and what they don't.
