| A lecturer was giving a lecture to his students on stress management. He 1 a glass of water and asked the audience, "How 2 do you think this glass of water is?" The students' answers 3 from 20g to 500g. "It does not matter on the absolute 4 . It depends on how 5 you hold it. If I hold it for a minute, it is OK. If I hold it for a(n) 6 , I will have an ache in my right arm. If I hold it for a day, you will have to 7 an ambulance. It is exactly the 8 weight, but the longer I hold it, the 9 it becomes." The whole audience became silent, lost in thought. After a moment, the lecturer continued, " 10 we carry our burden all the time, 11 , we will not be able to carry on with the burden becoming increasingly heavier, 12 heavy for us to bear." "What you have to do is to 13 the glass, rest for a while 14 holding it up again." As is shown in the story above, we have to put down the burden periodically, 15 we can be refreshed and are able to carry on. So before you 16 home from work tonight, put the burden of 17 down. Don't carry it back 18 . You can pick it up tomorrow. Whatever burden you are having now on your 19 , let it down for a moment if you can. Life is short, 20 it! | ||||
