I'm a little late to the thread and it's good to see so much encouragement. First off you are well ahead of where most people would be after 2 years. My only critique for your solo like others is the fluidity. My advice is that once you are up to the point is to learn how to play it faster than the original recording, if you can do that then playing normal speed will feel effortless. I don't want too take you're words out of context but if your main motivation to pickup the guitar is to do focused learning for an hour a day you will get burnt out. I think you either need to find a new motivation, that can be learning a new style of music, writing music, playing with others or something else entirely. Learning something for the sake of a general interest will eventually get old and become a chore. I am currently studying a degree in maths, there are topics that I find interesting and some that I don't. Luckily I only spend so long on each one before being assessed and moving onto the next thing so I enjoy the interesting ones and tolerate the rest. Until recently I hated statistics, first and foremost it's boring and secondly I didn't see a use for it other than lining the pockets of some corporation. Now I work part time for a non-profit organisation as a data analyst and I have a new found appreciation for statistics. Now I want to learn more because I'm applying it to something that actually makes a real difference to people's lives. My point being that to make real progress you need some real motivation that won't dwindle.
