When you're in the grip of frustration, love can seem pretty much out of the question. Care is going to be a stretch. But appreciation is easy-even if it starts out kind of snide like, "I appreciate the fact I haven't fallen flat on my face ... yet." After a couple of stabs at it, you're going to stumble across one that sincerely touches you. Maybe it's your friends, your partner, your loved ones. One strong dose of appreciation can turn your perceptions around 180 degrees.
