I agree with the vast majority of what he says...with a few qualifications.
It's tricky (for a beginner especially) to recognize a good teacher (or the right one for you). A great tip from the vid is a good one should listen and watch you play and teach accordingly. The three I've had that really helped me, did just that (all with 30yrs+ teaching and degree's in music). The 'worst' ones just tried to stuff what they were busying learning down my throat without even caring where I was on my musical journey.
DO JAM with other people. That where you get to try out you newly learnt stuff and try it in real life situations. See what works, and what doesn't.
It takes time to develop technique - muscles need to be developed - so hitting a lesson every week might be more of a hindrance that a help. Whart worked for me, was commiting to a arc of lessons to learn something specific, I'd work on it for a few weeks/months and then go back for review and another set.
You need to be be your own teacher - noone is spoon feeding ya, critical self-review of where you are at and what you what/need to learn is important. Though, a good teacher does help with this process.
Happppy learning peeps!
