Exactly!

CAPRICORN (Dec. 22-Jan. 19): "There are two rules for ultimate success
in life," wrote L. M. Boyd. "First, never tell everything you know." While
that may be the conventional wisdom about how to build up one's
personal power, I prefer to live by a different principle. Personally, I find
that as I divulge everything I know, I keep knowing more and more that
wasn't available to me before. The act of sharing connects me to fresh
sources. Open-hearted communication doesn't weaken me, but just the
reverse: It feeds my vitality. This is the approach I recommend to you in
the coming days, Capricorn. Do indeed tell everything you know.
