LEO (July 23-Aug. 22): "Insight is not a light bulb that goes off inside our heads," says author Malcolm Gladwell. "It is a flickering candle that can easily be snuffed out." That's a constructive warning. On one hand, you soon glimpse new understandings how the world works and what you can do to make it serve you better. On the other, be extra alert for these new understandings and committed to capturing them the moment they pop up. Articulate them immediately. If you're alone, talk to yourself. Maybe write them down. Don't assume you'll be able to remember them perfectly later when it's more convenient.
