Broad lines and values

In my work and personal development, I try to discover the driving forces, which often remain below the surface. What drives the strong growth of our mobility? Why is GDP still the indicator of social progress? How can teams and organizations perform better with greater work satisfaction? What drives each of us? In this quest I make use of the rich store of knowledge, insights and experiences gained by others. So I nosed around in areas such as behavioral psychology, communication, management, team building, economy, political sciences and of course the rich lessons of history.
Understanding the forces and interests behind the developments and changes, I see as a basis to redirect developments effectively. If we do not know how the system works, we do not know how to intervene. Policy will then rather be PR than really change the course of developments. And reorganizations will follow each other without improving the organization substantially.
