When the planet of action and energy (Mars) moves into the sign of royalty and exhibitionism (Leo), you can bet there's going to be excitement.
From August 27th to October 15th, Mars will activate and energize all Leo themes: pride, performance, ego, creativity. Mars is aggressive and impatient. The section of your chart with Leo in it will get fired up, and you may find yourself pushing for more because you deserve it.
This is a fantastic influence for elevating efforts above the ordinary. Setting your sights on the Big Romance, Big Promotion or Big Performance. Watch out for Big Drama...this sign/planet combination can trigger fights that are based on wounded pride. But for the most part, this is an optimistic influence that favours success and beating the competition. Even if you don't normally ooze confidence, Mars may stir some up for you (in the Leo section of your chart).
The one, brief shadow on this shiny aspect will be Mars' square to Saturn at 7 degrees Scorpio, from September 3rd to September 9th. Saturn's limits may slow your efforts, or make you feel like every action you take is wrong. This will be the time to dig in and work harder. Mars square Saturn is about beating the odds. Proving you've got what it takes. It will be the test for whatever started when Mars first entered Leo. If what you're going after is truly golden, this aspect will make it that much more precious (because you'll have to earn it). But if you're chasing after something that's all flash and no substance, this aspect will show you the reality of the situation.
Trust Saturn to spell it out.
