Mercury in Leo is currently opposing Neptune retrograde in Aquarius. When fantasy (Neptune) challenges knowledge (Mercury) you get the dual potential for creativity and deception.
Leo oozes creativity and drama to begin with. Throw in some Neptune flavored with revolutionary Aquarius and you've got crazy inspiration. Aquarius also represents the collective so you'll feel like trumpeting your awesome/audacious plan to everyone who will listen. Especially if it's something you're revisiting.
But that Neptunian deception bug bear is always lurking and it's going to be really difficult to assess if what you "know" is for real. What to do?
Write it down then tuck it away until September 9th. Mercury will move into Virgo and you will know immediately if what you've got is solid. Virgo is the fact-checker so any missing/ridiculous bits of information will come to light. You can then discard or move ahead with your brave new plan.
