How does Carlos Ghosn (rhymes with "phone") find the bandwidth or will power to account for 10% of all cars sold worldwide and $140+ billion in sales expected this year? By embracing the cultural differences, and applying discipline, discipline, and more discipline to his life–to the point of living "almost like a monk."
That translates to having reliable staffers around him who choreograph his schedule 15 months out. He is also able to focus solely on each company when he's in the respective country headquarters.
Even though Ghosn was once the subject of a comic book in Japan, he's certainly found a winning formula for Nissan--he's credited with turning the company around over the past 12 years. In his own words: "You need to make sure you are where you think you are indispensable, and dedicate your task to that." It's a good lesson for managers everywhere.
