Thanks for writing Steve and great questions! First off, it's never too late in life to start playing guitar. In fact it's a great exercise for our brains with the coordination between left and right hands and all the memorization that is required. Practicing 2 hours every day is great, but you'll want to make sure you're practicing the right things and in the correct way. A good practice routine should include about 20 minutes of warm ups - finger exercises, scales, and scale exercises that should be played with a metronome and keep track of your tempos. The next 20 minutes should be working on techniques like tremolo picking, hammer-ons, pull-offs, trillIng and any other techniques specific to the songs you are working on (like sweep picking, tapping, string skipping, hybrid picking, etc.). Follow this up with about 20 minutes of jamming/improvising over backing tracks from the Guitar Tricks site (in the 'Toolbox' under 'Jam Station') to put together all that you've learned so far (scales, licks, and techniques). The final time should be about 30 minutes on a song of your choice (work on the tricky spots and memorizing the song).
