I have created a methodology called ‘Affairs of the State’. Actually it is not so much a creation, but an adaptation.
‘Affairs of the State’ refer to the Book ‘Art of War’ by Tzun Tzu (Chuang Tzu). Though this book has been used by many warlords to ‘apply’ to war or conflict situations. I think it is usable in every situation of your personal life. Yes, there are books explaining how to ‘adjust’ leadership for manager, by applying it. But this is still limited and (because it is a ‘western’ use of ‘eastern’ knowledge) a failing adaption for improvement.
