A Waning Sextile between the Aquarius Moon and Aries Sun (21 deg) is an opportunity. Odd ideas, glimpses of freedom and the urge to set your own rules should be followed up on - they are hints about what lies ahead.
Innovation mixes with courage: don't be afraid to turn left. This won't be a powerful vibe. It's more like a light glimpsed out of the corner of your eye. You can ignore it, or turn towards it and watch things accelerate.
This aspect can help you move through the tension of the Third Quarter Square. It's still dark (and getting darker, because the Moon is decreasing in light) but think of this sextile as your headlight.
