Think of two words that are meaningful to you, that will make you feel calm, yet inspired. Close your eyes, and as you inhale slowly, think the first word in your head. As you exhale slowly, think the second word in your head.
For example: inhale gratitude, exhale kindness or inhale love, exhale peace. Just keep breathing deeply, thinking these words to yourself. If your mind starts to wander, just come back to the breath and back to these two words.
