The way we spend our time can be divided into three "bottles"．These are the necessary tasks bottle，the voluntary（自愿的） tasks bottle and the happiness bottle．

Every day，we spend time filling the necessary tasks bottle with useful things，like making money，doing housework，buying food and paying bills．We then fill another bottle with voluntary tasks．These are things that we do for others，but we may not enjoy them．This bottle gets filled with tasks like taking children to activities，cooking family meals，and doing laundry．Those bottles are very important．If we don't fill them each day，our family won't run properly．

However，we often forget to fill the third bottle﹣﹣﹣﹣the happiness bottle that we fill with activities that make us happy．Is your happiness bottle sometimes empty at the end of the day？Between doing all the necessary and voluntary tasks，time flies by，and before we know it，it is time for bed．We all have days like that．

This is why each day we have to make an effort to fill our happiness bottle．I fill mine by going to the dancing class．And I always leave classes more happily than when I enter．This week，I had the pleasure of taking part in a guitar practice in my neighborhood．We show our musical talent and practice music for charity．It was a time of fun，friendship and music﹣making．At the end of the evening，my happiness bottle was filled to top．

            Will your activities bring joy to your life？Or are the other two tasks eating up all your time？Try to find ways to achieve a balance between how you fill your three bottles．At the end of the day，hopefully we've done all we can to make sure that our happiness bottle is filled．
