A calmer disposition can be as easy as taking a breath...
Ruled by the Moon means you're subject to being influenced by the moods of others. At worst, that can add to your anxiety. At the least, it can sap your energy and divert your attention.
Lucky for you, the solution is only a breath away. Inhaling and exhaling fully and deeply can instantly boost your energy, relax your body, and help you be more alert.
Your sign rules the lungs, so you should use them to their best advantage! If you're feeling on edge, breathe through your nose and draw air deep into your lungs, allowing your diaphragm to contract downward.
Exhale and push the carbon dioxide out of your lungs. Repeat. You'll feel better in no time!
