A suggestion if I may: When you receive the course, go from page 1 to the end, step by step. Record yourself along the way. Keep a logbook of your progress, when you played and what the lesson was, as well as your own comments on the lesson.
Don't be like some members, who "collect courses", which helps Griff's sales, but does not add to your guitar knowledge. There is something about fingerstyle, and acoustic guitar that is really a great deal of fun.
If and when you should go to an electric guitar in the future, you will have many things to concern yourself with. Besides attempting to determine which courses to obtain, you have to contend with what color guitar, pickups, strings, bridge, nut, frets, neck, body, tuners, picks, strap, amplifier, speakers, pedals, and the list goes on.
The world of acoustic guitars can be so much simpler than the above!
An acoustic guitar is like a good friend. Keep it and enjoy its company. It is always there for you to enjoy. You do not have to concern yourself with emulating the sound of someone else. You are your own boss.
