Specialization is for insects

I keep this passage above my desk for inspiration. I'm repeating it here for posterity. It was uttered by the Robert Heinlein character Lazarus Long in Time enough for love.

"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, fight efficiently, die gallantly.
