The wish for adventure and the wish to keep something going can be there together.

Yes. It is more than looking only into the distance or only at your feet. Receive what you find and give it a form that you or someone else can use. December connects the strength to explore with the strength to nurture.

A different perspective can help the relationship grow.December is an even-numbered month. Other even months share a familiar rhythm of receiving, connecting and arranging: what we call resonance. With odd months, understanding differences in the speed of taking initiative can provide inspiration. We call that a rival connection.

December love wants to move freely and still have promises it can trust.

You need not give up either. Even with wings that can travel far, having somewhere to return to makes flying feel safer. A love that nurtures both your freedom and promises you can come back to suits December.
