I know this is a subjective question and impossible to answer, but how long does everyone think a beginner should stick with each lesson before moving on? I'm currently on Chapter 3, An Introduction to Chords, and practicing the 4 chords.

I don't want to spend weeks practicing the four chords over and over but neither do I want to rush ahead and not get the basics right, especially as I'm not moving cleanly between chords (mostly with A Minor).

Any thoughts?
