Wow, Justin with his hair!

Been plucking at the guitar (literally and figuratively - trying to learn) for a couple of years now and Justin's (free) course was the best I've found. His videos are compassionate, funny, explain things really well and easy to follow. He also dog-fed the instructions by learning to play left-handed (and posted those videos as well, hilarious to watch).

Compared to that, some time earlier I subscribed to a Berklee free course on Coursera (iirc) - Beginner guitar. Felt like a fumbling idiot, almost never touched guitar afterwards.

Really recommended: https://www.justinguitar.com/
