I may be a dreamer

Last paper for the Fall Semester tomorrow; yesterday, while I was trying to study for the Investments exam, I remember wandering off...
I was sitting on the couch, gazing away and talking to myself. When I regained consciousness, I realized that I had been talking and mumbling to myself for the past, may be, 45 minutes (OK, may be 30). I laughed and started singing, "You may say I'm a dreamer, but I'm not the only one." Then thought for a fraction that may be I am the only one; then again, there are too many humans, so I don't think I would be the only one.
I grow afraid that I may be a dreamer and not a doer. Than again, I know that when I set my mind to something, I do become a doer.
