Mike, i just joined as well, and am about your age.
I have been playing about 5 years, and have diligently practiced, but have not practiced smart.
I have jumped around, and tried to learn everything!! I am going to hitch my wagon to Pebber and try to maintain a sensible and constant path to this.
I have learned a lot of what not to do, let me know if i cam help you in my limited way.
I use a book called guitar aerobics, it has a daily ( for me =Weekly) practice schedule. I like it very much. I also use a program called You Tube downloader ( YTD) to make videos on my computer from you tube.
The main thing I have learned, and would do right the first time if I had another chance, is hand mechaninc's. The bad habits are pretty hard to shake later on!! Thumb position, wild fingers flying up, etc.
We can do this!!!
