Imagination: the power to find alternatives

Some of our most despondent moods are caused by failures of the imagination. Imagination here is the power to envision alternatives. When we're sad, we can't imagine finding other work. We can't imagine getting by in a wheelchair. We can't imagine having to make a new set of friends.

With sufficient imagination, we can find possible solutions. If Plan A has failed, we can look to Plan B or C.
