Stargaze. Have a look at old photos. Draw or paint your favourite place. Take a drive or walk to somewhere new.
Eat dark chocolate. Make herbal tea. Make a home-cooked meal. Use fresh herbs in your cooking.
Buy fresh flowers. Light an aromatherapy candle. Bake a cake or bread. Smell fresh herbs. Wear your favourite scent.
Get lost in music. Call up someone you love. Listen to the sound of the sea. Listen to the rain.
Give yourself a massage. Wear soft fabric. Caress your face. Give yourself a hug.
