In a hall, a lecturer was giving a lecture to his students on stress management. At the beginning of the speech,he 41 a glass of water and asked the audience, “How 42 do you think this glass of water is?”

The students’ answers 43 from 20g to 500g.

“Actually,it does not matter on the absolute 44 . But it depends on how 45 you hold it. If I hold it for a minute, it is OK. If I hold it for a(n) 46 , I will have an ache in my right arm. If I hold it for a day, you will have to 47  an ambulance. It is exactly the 48 weight, but the longer I hold it, the 49 it becomes.” Hearing these words,the whole audience became silent, lost in thought.

After a moment, the lecturer continued, “ 50 we carry our burden all the time, 51 , we will not be able to carry on with the burden becoming increasingly heavier,  52 heavy for us to bear.

“So, what you have to do is to 53 the glass, rest for a while 54 holding it up again.”

As is shown in the story above, we have to put down the burden periodically, 55 we can be refreshed and are able to carry on.

So before you 56 home from work tonight, put the burden of 57 down. Don’t carry it back 58 . You can pick it up tomorrow.

Whatever burden you are having now on your 59 , let it down for a moment if you can.
