Beginner Guitar Teacher

This question came in from a reader - it’s a great question because every guitar teacher struggles with this when they’re starting out: I am struggling to judge how much to cover in a single lesson - both the lesson itself and itself and the homework / practice assignments. I don’t want to overwhelm a student, but I would also like to offer variety of areas to work on. I recognise that a lot of this is down to the individual, but wondered if there were any general pointers.
