When you're practicing, or even when you're picking with other folks, remember to play your old tunes too. This does several good things. Among them: (1) You keep your fingers playing a wider variety of licks and melodies. (2) Your friends will enjoy the variety when you dig up a tune from the past. (3) You have the pleasure of re-discovering a great tune or song you'd almost forgotten.
But one of the best things about picking your old tunes, is that it keeps your brain working. If you play just half a dozen or so songs all the time, it's easy to get into a musical rut and stay there for years. Instead, consciously go back and find tunes and songs you used to play. Keep learning new tunes too. Go through our Slow Jam DVDs and remember some songs you used to like. Your brain will like it, and your picking friends will thank you for it!
