You’re making important decisions about your future and what you want to focus on what’s next.

There’s a Full Moon in Gemini on December 4 that starts the month out on a dramatic note. You’re full of ideas and chattier than ever. You might have an important conversation you’ve put off, sign a new contract, or learn something that rattles your comfort zone or previous understanding of the world around you. This is a moment to grow, learn new things, and open your mind.

You’re feeling worn down when Mars in Sagittarius slams into Saturn in Pisces on December 8. This is not the time to overcommit and push yourself. Slow down, listen to your body, and rest if possible. You might need to tell someone no or to take a personal day. Conversations can also feel disappointing or isolating in some way. Just know this energy is temporary! You’re feeling more hopeful once Mercury moves into Sagittarius on December 11—you might be ready to book a trip! The next few weeks are also a great time to learn a new language, sign up for a workshop to learn a new skill, or to reconnect with your voice by working on writing projects or starting a podcast!

You’re busy chasing after your dreams once Mars moves into Capricorn on December 14. The next few weeks help you bring some of your visions to life and can also help you advocate for yourself along the way. You might need to set important boundaries at work or with loved ones. More responsibilities could pile up on your plate, but you know the payoff will be worth it in the end. Misunderstandings also finally begin to clear once Mercury exits its post-retrograde shadow period in Sagittarius on December 16. You can let out a sigh of relief and stop triple checking all of your texts before hitting send.

On the same day, the Sun in Sagittarius rams into Saturn in Pisces, reigniting some feelings of exhaustion. You might feel under appreciated or like you simply could use some time off! Give yourself a break and just know you might be a little bit more irritable today.

A new moon in Sagittarius on December 19 invites you to speak your truth. You’re ready to set an important boundary or share what’s been on your mind, even if it feels uncomfortable. This is your moment to discuss expectations now in your relationships and at work, so you don’t feel taken advantage of down the line.

The Sun enters Capricorn, and the Winter Solstice takes place, on December 21, bringing recognition and applause your way. You’ve worked so hard to get to where you are now, and this is a reminder to enjoy the present and celebrate yourself and your progress. You could also be up for a raise or promotion, or make meaningful progress toward a longterm personal goal. Use this momentum and attention to your advantage.

There’s some more luck on your side once Venus enters Capricorn on December 24—this brings more support your way. New contracts and relationships could enter your life. You might take the next step with a lover or experience a supportive period at work or in your key relationships. You’re also more magnetic than normal and your manifestation skills get a boost—so make the most of it!
