^A psychologist walked around a room while teaching stress
management to an audience. As she raised a glass of water,
everyone expected they'd be asked the "half empty or half full"
question. Instead, with a smile on her face, she inquired: "How
heavy is this glass of water?"
Answers called out ranged from 8 oz. to 20 oz.
She replied, "The absolute weight doesn't matter. It depends on
how long I hold it. If I hold it for a minute, it's not a
problem. If I hold it for an hour, I'll have an ache in my arm.
If I hold it for a day, my arm will feel numb and paralyzed. In
each case, the weight of the glass doesn't change, but the
longer I hold it, the heavier it becomes."
She continued, "The stresses and worries in life are like that
glass of water. Think about them for a while and nothing
happens. Think about them a bit longer and they begin to hurt.
