Some people work to put food on the table and a roof over their head, others perhaps to realize a dream. Regardless of why we work, our occupations change over time. Who today knows what a shoe closer is and who in the 1800s had been able to imagine that "barista" is a job? Maids, IT consultants, tracklayer - lots of people have gone to their jobs every day. Perhaps it is just as difficult to get out of bed in the morning whether you are taking the car to Atlas Copco in 2015 or walking to the REX shoe factory in 1925.
