What courses do you have? In all of the courses I have from Griff, he constantly preaches that you need to count out loud as you play. Especially in the beginning. Do you have the Strumming and Rhythm Mastery course? I've also heard that the Beginning Blues Guitar is an excellent starting point to build strong fundamental guitar skills. If you don't already have these two courses, do what you can to get them. You will not regret it and they will help you immensely.
