Any Other Guitarists in the House?

<p>Okay, so I recently picked up my mom's old Aria acoustic guitar and decided to teach myself to play it.</p>

<p>Now I was at a slight advantage because I've been singing for 9 years so I can read sheet music, but I'm having a lot of trouble being able to switch between chords without losing a beat (I've been working on it for a couple months now). Any advice from anyone to help my fingers be more nimble would be greatly appreciated.</p>
