Work that results in something lasting will be more enjoyable than work of temporary nature.
A farmer, construction worker, boat builder, carpentar or any similar professional has the ability to create something he can look at, something that can be seen, touched, used and benefitted by dozens, hundreds or even thousands. Like the rice farmer constructing and caring for these rice terraces who can make a break and look at his beautiful work and actually see the fruits of his work growing and bearing fruits or harvest for others.
