Not sure if this applies to you, but from my peronal experience I have been messing with guitars on and off for years and always failed to achieve any level of competence.

I have had several teachers who were great guitar players.

However I never really got anywhere, I practiced scales, learnt theory and so on and was always pushed to improvise but in the end after many attempts of trying and failing I couldn't play a decent tune, not to any level of competence anyway.

This is my final attempt but it has dawned on me I have never really got to grips with rhthym. Non of my teachers really pushed me in that direction and I could not count the beat, not at all, not when playing anyway.

After joining GT and working my way skipping most of the foundation I have started on the Rock part 1 which covers rhthym foundation quite well and I am beginning to get to grips with time keeping and being able to count whilst I play. It is not easy but I think my playing is improving because of it and I can now use this in other studies.
