So, after stumbling over Emilie Wapnick's TED-talk, I began referring to myself a "multipotentialite". It resonates with the quote I consider being a recap of ultimate work-life integration (not balance):
“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 ['insects' may be replaced with 'robots’].”
