A good and worthwhile question. I hope it gets some thought from many members.
I would add any of the following to your list of vital skills:
Serious fighting/combat/self-defense
Public speaking
Basic engine/machine repair and maintenance (change the oil, replace spark plugs, etc...)
Basic arithmatic (perfomred in your head, not on a calculator)
Cooking
Ballroom dancing
Hunting and/or gardening
Accounting
There's more to being a well-rounded man than simply possessing skills. You should have a wide body of knowledge. Humanity has learned an awful lot over the years, and you should grok most of it. There's no excuse for not knowing what our semi-primative ancestors knew hundreds of years ago
Shakespeare, calculus, Mercantilism, Newtonian mechanics, Latin (or Greek), Battle of Watterloo, Beethoven's 9th, Marcus Aurelius, Rodin, participles, Jefferson vs Madison, and on and on and on...
All of these tyes of things should mean something to the educated man. He need not be expert in all cases, but he should be able to hold up his half a convsesation about any of them.
If you wanna take it one tep further, you could even draw up a list of experiences a well-rounded mand should have. A few valuable experiences that come to my mind:
Living in a foreign culture
Being well and truly poor
Working/volunteering in a hospital
I'll add more later after my brain has had a chaince to stew for a while. Good question, though. I like it.
