Why do people do what they do?

Ever wonder why people do what they do? Seriously, think about for second. Why do people do what they do? Why do people wake up in morning just so they can go to work? Why do people work for that matter? Why do people spend more time working than at home? Why? Why? Why? Why do people put up with boss? Why do people pretend that they love their job even though dip down inside they really hate getting up every day to go work? Why do people call it a work?  

Now let imagine our world with perfection (lets say a haven) where people don’t have to worry about food, money, home or anything for that matter. Anything and everything you imagine is your.  Would people really work then?  Lets say some stubborn people did choose to work even in perfect world,  I ask again, why do people do what they do?

On the other hand, why am I writing this?  For that matter why are you reading this?
