Seneca recommended this practice in his letters, and Epictetus taught students to reflect on impermanence to cherish the present.
How to Practice
Choose something you value deeply
A person, your health, your home, a relationship. Pick something you might ordinarily take for granted.
Gently imagine life without it
Hold the image briefly. How would your days feel? What would you miss most? Let the feeling arise naturally.
Return to the present moment
Open your eyes and notice that this thing is still here, right now. Feel the quiet relief and warmth of having it.
Express gratitude inwardly or aloud
Say thank you — to yourself, to life, or to someone you love. Let the appreciation settle into your body.
