I'm holding the glass of water with my left hand,because I am left handed .The water measures just half of the glass.So,what is the weight of this glass of water that I'm holding now?Being passed on by several people in this room,none of the liquid in the glass spilled out.Everyone who had hold it knows that the answer ranges from 8 oz. to 20 oz.
Still holding to it,I realize that the actual weight does not matter.It actually depends on how long do I hold it.
Holding it for 1 minute is easy.Hold it for an hour,I will have ache in my arm.Hold it for a day, my arm will be numb and paralyzed.Notice that the weight of the glass does not change,but the longer I hold it,the heavier it becomes.
Stress and worries in life is like that.Think about it for a minute,nothing will happen.Think about it for an hour,they begin to hurt.If you think about it all day long,it will make you feel paralyzed and incapable of doing anything.
