AQUARIUS (Jan. 20-Feb. 18): "One should be light like a bird, and not like a feather," said French poet Paul Valery. How do you interpret that? In the book "The Science of Self-Control," here's how Howard Rachlin expands on Valery's idea: "We need to be spontaneous, but only in the context of some framework that allows us to attain higher levels of spontaneity; a feather is a slave to the wind, while a bird uses the wind." Take heed! Creative flights go further and last longer if you have a solid foundation.
