We fill this jar with useful things，like making money，doing housework，buying food and paying bills. We then fill another jar with voluntary tasks like taking children to activities and cooking family meals. Those jars are very important，but we may not enjoy them. If we don't fill them each day，our family won't run properly.However, we often forget to fill the third jar一the happiness jar. This is the jar that we fillwith activities that make us happy. Is your happiness jar sometimes empty at the end of the day? We all have days like that. Between doing all the necessary, and voluntary tasks，time flies by on some days，and before we know it，it is time for bed. That is why each day we try to fill our happiness jar. Most days，I fill mine by going to the ballroom dance(社交舞)class. Playing music is another way that I fill my happiness jar. This week，I was happy to take part in an orchestra(管弦乐队)practice at my church(教堂).At the end of the evening, my happiness jar was full.Consider how. your time is spent. Try to find ways to achieve a balance. At the end of the day，hopefully we've done all we can to make sure that our happiness jar is filled.1.What will happen if we don't fill the necessary tasks jar and the voluntary tasks jar?______________________________________________________________________________2.How does the writer fill her happiness jar?______________________________________________________________________________3.Do you think it important to fill the happiness jar?
