Agreed, that power chord in the first lesson of the 30 days was daunting. But I felt it made the next days feel easier.
Did you download the 30 day guide? It’s 70 pages and has a bunch of useful info about holding the guitar towards the beginning along with video links. I found it helpful when trying to figure out why my back was hurting – definitely called it my guitar injury for a week or 2 :).
