"I've had a lot of worries in my life, most of which never happened." Mark Twain
Nearly being deprived of small, simple pleasures has heightened our appreciation of them. I recall a client, who found counting three blessings before getting up in the morning, helped her manage the domestic chaos that awaited her outside the bedroom door. I know of people who chose to do something similar at the end of the day.
Not living for the day, but in the day.
