Write every day about your good memories from the past 24 hours.
Write every day. Once, for at least ten minutes. If you feel you can elaborate, continue writing.
Write about your good memories from the past 24 hours. Someone said something nice about you; you accomplished something that showed a commendable skill; you demonstrated intelligence, wisdom, or kindness, or you simply enjoyed something. You recalled and reflected on a virtue or a good deed you did in the past. Write about all of that. Try to elaborate and even exaggerate if that trait is the complete opposite of what you believe about yourself. You can write less if you already see that positive aspect in yourself. Write in the sequence of the places and times you moved through during your day.
