Strong work ethics -- just plain common sense?

So what makes "common sense" so common?  It's the good sense that you were born with -- right?  But who says so? Did you know that it's rude for a guest to wear their shoes inside when visiting someone's home in Japan?  Well everyone in Japan knows. On your next trip to eco-friendly Sweden how long would it take you realize that you are expected to bring your own reusable shopping bag to the grocery store? 

For many of us, when we were  very young we learned our ideas about  work from the people and circumstances we grew up in and around.  Work was a foreign and mysterious place inhabited by grown ups while we went to school.  Observing the daily discipline of my parents getting up and going to work each day, sick or well, rain or shine, shaped my earliest ideas about what it meant to have a job. If I hadn't observed their routine and heard their conversations about day-to-day life in that other world away from home where they spent 8 hours a day, what would I have come to believe on my own? I mean, there's really nothing natural about feeling compelled to get out of your sick bed to go to work when you'd honestly feel better staying at home. How about resisting your best friend's temptation to bail out of going to work on a sunny summer Saturday morning?  Unnatural!  What's most common in all of us is the preference to do what's comfortable and enjoyable given the choice.  Human nature -- that's what we're all born with. 

My parents' instruction and example demonstrated so many lessons, spoken and unspoken, that school  work and real work had far less to do with how comfortable it was at the time, than what I planned to get out of it in the long-run.  They weren't born knowing this. No one is.  They had learned it all from their role models, the language and cultures of the places they had worked and from life in general.  Today those lessons vary greatly among different generations, households, neighborhoods, geographic regions and other ways in which people differ. Fortunately, there is often more than one way to learn any good lesson.
