But hey, it's a hobby ... so enjoying it and never feeling like it is a burden to practice is important for me.
Exactly. Keep playing, have fun with it. Become a bit frustrated when things don't seem to work, pick yourself and the guitar back up and move on with it. Perhaps an easy goal could be: I want to be the best player I can become by practicing at least one hour a day.
Or if you want to be even more specific: I want to be the best blues/rock player I can become by practicing at least one hour a day.
Anything you do can work towards that. The 5 minutes of this, 5 minutes of that would make it almost like a job for me.
