I should really be asking the opposite. Should I complete guitar fundamentals 1 as I've only learned 6 or 7 songs and many parts of a few other songs 😁

My learning style is all about fun. If I'm not enjoying it I'll just give up. The enjoyment comes from playing songs, even just parts of them.

I'm off to have a go at Starting Over and Fox on the Run. There must be some fundamentals in there somewhere.
