It used to be helpful if you could milk a cow, cook a meal from your garden, make your own clothes, build your own house, and teach your own children.  Then, we went through the industrial age during which everyone specialized.  "We can accomplish more if you get really good at tightening that screw and let the next guy do the next step."  It seems we have lost a lot of the connections in the world.  

When I talk to my husband about my day, he will often ask me, "Why don't you focus on ONE thing?"  That seems like reasonable advice since I am making clothes, writing a book, creating a photo essay, pursuing relationships with friends and neighbors, studying many facets of God and the world, and taking care of my children (which involves a lot of cooking, cleaning, driving, and talking).  However, to me, that all seems CONNECTED.    

Each activity speaks to the other.  They influence each other and make each activity better.  If I quit one, another would suffer.  Varied interests makes our lives richer.  

"A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.  Specialization is for insects." - Robert A.
