According to Robert Heinlein, a human being should be able to:

•   Change a diaper (I’ve done this too many times already)
•   Plan an invasion (I don’t know; does Axis and Allies count?)
•   Butcher a hog (I’ve not done is solo, though. Just helped)
•   Conn a ship (A boat, actually, but I’m counting that)
•   Design a building (Sure, but that doesn’t mean it was built)
•   Write a sonnet (Several in fact)
•   Balance accounts (Yes, but I didn’t like it)
•   Build a wall (Lots)
•   Set a bone (Have not been in a position where I’ve had to. That’s fine with me for now)
•   Comfort the dying (Yes)
•   Take orders (Lots)
•   Give orders (Some)
•   Cooperate (Usually)
•   Act alone (When I want it to actually get done)
•   Solve equations (For fun and profit)
•   Analyze a new problem (All the time)
•   Pitch manure (Oh heck yeah; cow, horse, pig, and chicken)
•   Program a computer (Morning, noon, and night)
•   Cook a tasty meal (Yes, but my wife says not often enough)
•   Fight efficiently (Have not had the need to really)
•   Die gallantly (I have to admit that I’m sort of dragging my feet on this one)

For as he says, “Specialization is for insects.” I feel like I’m doing pretty good so far.
