If you've got great rhythm, then this means if you decide to branch out to Lead Guitar, Fingerstyle, Ukulele (anything where strumming might be involved) your timing will be good and subsequently you'll sound so much better. Its a good idea to focus on your rhythm, and make sure its "tight" and you can change swiftly and smoothly from one chord to the other. Whether its basic chords or Barre Chords and Power chords try and get youre rhythm as "tight" as you can.
