Management Since 1800
I’m a proponent of leadership over management as the primary course of study to improve one’s ability to influence people. Management, however, seems to have reigned as a subject in books since the 1800s. The google Ngram below charts the usage of the keywords “manager,” “leader,” “management”, and “leadership” in books since 1800.
I notice a couple of interesting things about these trends:
- Leadership subjects did not appear until the mid 1800s (perhaps as a result of the American Civil War)
- Management subjects decreased during the America’s Great Depression
- Management subjects skyrocketed during 1970-1990 (the rise in the economies of industrialized countries)
- All of the keywords dropped in usage after 2001 (Influenced by the attacks on September 11?)
Heaven vs hell

Gratitude Unlocks the Fullness of Life
Gratitude unlocks the fullness of life. It turns what we have into enough, and more. It turns denial into acceptance, chaos to order, confusion to clarity. It can turn a meal into a feast, a house into a home, a stranger into a friend. Gratitude makes sense of our past, brings peace for today and creates a vision for tomorrow. – Melody Beattie
Real Life
Real life isn’t always going to be perfect or go our way, but the recurring acknowledgment of what is working in our lives can help us not only to survive but surmount our difficulties – Sarah Ban Breathnach
Your Real Life
The great thing, if one can, is to stop regarding all unpleasant things as interruptions of ones “own” or “real” life. The truth is of course that what one calls the interruptions are precisely one’s real life – the life God is sending one day by day. – C.S. Lewis
Tomorrow, A Hundred Years, a Thousand Years: All the same
The next moment is as much beyond our grasp and as much in God’s care as that a hundred years away. Care for the next minute is as foolish as care for a day in the next thousand years. In neither can we do anything, in both God is doing everything. -C.S. Lewis

Team Leadership
My philosophy of leadership is that four or five of us can come up with a much better decision than just I can alone. And if you follow that philosophy, you’ll probably have a very good, talented management group around you. People can always perform a whole lot better than how you think they’re going to perform. You need to really give them the opportunity to do that.
