Contemplate gratitude. Every day, when you wake up, express three things for which you are grateful. Perhaps you have a job you love. Maybe you have a very supportive partner. You might have no illnesses. Always taking a moment to reflect on the things for which you are grateful can be very helpful.
See Express Gratitude for ideas on how to express your gratitude to others.
Practice counting your blessings before bedtime by journalling about three positive moments from your day. Contemplate why these moments occurred and what actions of yours did or did not lead to them
