A lecturer was giving a lecture to his students on stress (压力) management. He        a glass of water and asked the audience, “How           do you think this glass of water is?”
The students’ answers ranged (变化)           20g to 500g.
“It does not matter on the absolute           . It depends on how        you hold it. If I hold it for a minute, it is OK. If I hold it for a(n)           , I will have a pain in my right arm. If I hold it for a day, you will have to          an ambulance(救护车). It is exactly the           weight, but the longer I hold it, the         it becomes.” The whole audience became silent, lost in thought.
After a moment, the lecturer continued, “        we carry our burden(负担) all the time,          , we will not be able to carry on with the burden becoming increasingly heavier,           heavy for us to bear.
“What you have to do is to           the glass, rest for a while           holding it up again.”
As is shown in the story above, we have to put down the burden periodically,        we can be refreshed and are able to carry on.
So before you         home from work tonight, put the burden of           down. Don’t carry it back        . You can pick it up tomorrow.
Whatever burden you are having now on your        , let it down for a moment if you can.
Life is short,          it!
