I think it is far from wise to quit their jobs and stay idle after winning a lottery.Remember we humans are meant to work.
First,no matter how much money they may have won,they may sooner or later lose the money.Just like the saying,"easy come easy go".There is a Chinese idiom saying the same thing:Always taking out of the meal-tub and never putting in,soon comes to the bottom.
Second,we seek not only salary from our jobs,in fact,we seek chance of achievement or success in our jobs.We need to realize our dreams or goals in our jobs.We need to prove that we can do something useful and valuable to others and to the society.
Thirdly,it is a waste of life to be fool around.Life is actually too short for everyone.Doing something meaning will make life itself meaningful too.Having a job to do will mean a lot to anyone who wants to be active ,important and respected.
So,it is not wise to quit their jobs and stay idle or just enjoy the eaay money if they win a lottery.Life may be beautiful at the beginning,but in a long run,it is not worth wasting their life and time.
