Hi DaveC_42
What worked for me is setting goals and actually writing them down and tracking the progress. There is no better motivator than seeing youreslf reaching your goals.
I basically structure my parctice session in the following way:
Part 1: Techniques: Idntify what your weak points are on the guitar and work on them for a set amount of time for instance chord progressions that you are struggling with, alternate picking speed etc..
Part 2: Learn something new: Work through the structured system for a set amount of time starting with Fundamentals 1 & 2 and the moving on to any style that you are more interested in
Part 3: Learn ing songs: Learn a new song or practice a song that you have already learnt , work on improvisations etc..
The most important thing is to just have fun
Also if you are struggling with something specific, take a break from it for a day or two and then get back to it
You definetly chose the best platform out there for learning the guitar
Enjoy the journey
