For a pessimist, I'm pretty optimistic

From the very first time I saw you
I felt my whole life and it was all new
I felt my knees get weak, my heart went crazy
I felt some yes and no's I even felt some maybes
I'd climb a mountain top, I'd swim an ocean too
Get down on my knees only if it was for you
I think that I would about anything
You're in my dreams and in the song I sing
