If you have to do anything that requires a great deal of concentration, you might want to put your daydreams on hold. The line between what's real and what's not is blurred once again, but that's really not anything new to you, is it? If you have a lot of free time on your hands, however, feel free to dream to your heart's content. Something constructive might come out of your wishful thinking, but even if it doesn't, it's still time well spent.
