Try grabbing the guitar sometimes while watching the tube and just alt. pick open strings, then jump strings for a while. After that, capo a fret with your index finger while focusing on the program instead of what you are practicing. This is a great way to play by feel and train your ear to different sounds. In a short time you will feel it when you hit a sour note. Building dexterity even when your'e veggin will motivate your desire to learn new things because your picking techniques, ear and two hand coordination have moved to a higher level. Frustration comes from the mind because your fingers won't do what you you want them to. Sometimes you just have to ignore them and let your fingers do the walking like Jimi Hendrix did.
