I started out on a nylon string acoustic guitar for two years, and once I finally added an electric guitar to the family I was very unfamiliar with using a pick, but I got the hang of it. Its just that fingerstyle is a technique that I always felt the need to utilize, because it helps you get in touch with your instrument and the many possibilities. Many years later, I have dabbled in various techniques, but I'm very thankful for those early training years with fingerstyle, which gave me a much better appreciation for the instrument itself, as well as much needed patience to succeed. Its never too late to start with fingerstyle, its great for your coordination, and if you havent tried led Zeppelin's master piece "Stairway to Heaven" yet, you don't know what you're missing.
