I don't think you started too late. Well, in fact I don't think there's somthing like starting too late.

I didn't start with chords when I first started playing guitar. It's one thing I regret. I played metal so powerchords were my gods. Then I turned quickly to lead guitar.

I really started playing chords about 7 years after I picked up my first guitar. It took me about 6 months to really feel confortable and being able to switch chords with enough speed.

Don't loose your motivation and learn new songs on a weekly basis. At least one or two a week and you'll always want to play.
