I totally agree with the following statement.
Workers essential working hard during the workday, if they don't get the enough and nice retire ,the will feel very boring and get mad easily.In this situation, if they do the same work whole day, they will want to sleep .
If they do the same work like draw the picture whole day or design the building whole day or be the teacher talk for whole day ,they economic system will be worth ,but if they try another way which can let them be happy and meaningful, they will work so fast and complete very well so that make the surprise to boss or manager .
The other way is woke in different types. For example, if you are a designer ,you can design some buildings in sometimes,  draw some picture of buildings, read some building's books and find some key words or key sentences that are helpful for you ,you can also go outside to visit some famous buildings or famous people house to learn and talk with them or their house designer ,you will find that you didn't find before , this can help you to design different sytels and different kinds of buildings ,that's so amazing. 
If you are a teacher ,you can choose to teach thirty students once ,you can choose to teach ten students,and you can also choose to teach 1 students ,
