Oh I can relate to stalling on the hard stuff... I think I played through both books about three times before I finally found the courage to tackle the pieces with three flats
So far I'm liking book 3. It has a lot more theory and a lot less hand holding on pieces. I'm a little nervous about self teaching now and I realize there might be a point where I will regret not having a teacher.
But then I just keep telling myself that it's only a hobby... the moon will not explode because I'm not doing something 100% correctly. As long as I keep making progress, I'll follow this path You know the saying "you don't know what you don't know" but the opposite is true too... "what you know, you know!" And I know I'm not stuck just yet
