All Jobs are boring, bar none. (almost)

Innumerable times, I have felt that lot of humans are wasting their lives over pointless jobs. Probably they have very little other options. Look at waiter in the hotel. Imagine, how boring his life can be? Imagine a civil laborer,imagine a boiler operator, TV mechanic,....
Yes,Yes, I know one can make life interesting by learning something new all the time. How many people do that out of motivation, need or awareness? (learning someting new)
Rest continue with their mundane jobs, mundane lives. World is really in a pitiable state. :(
