If you wish to have more joy in your life, all you have to do is choose more joy. Know in each moment you have a choice, even when you don't feel as if you do. If you recognize you are not feeling joyful, consciously cultivate something that does bring you joy. Dance. Laugh. Listen to music that uplifts you. Play with a puppy. Hug someone. Tilt your face to the sun and feel its warmth. Seek pleasure and allow yourself to feel the joy of that experience. Then, carry that feeling of joy with you. If you notice it starts to slip away, find another joyful experience. Recall a cherished memory. Stretch in the most delicious way possible. Think of a funny joke. Hum a tune. Imagine yourself achieving your deepest desire.
Cultivating joy is about the small choices you make from moment to moment. If you notice you are annoyed, choose joy. If you notice you are sad, choose joy. If you notice you are angry, choose joy. If you notice you are afraid, choose joy. When you seek it, you'll find joy is always there just waiting for you to recognize it and bring it to the forefront of your experience. It is yours for the taking wherever and whenever you want it.
