It's a book. The Fifth Discipline.
Published in 1990, and it's about business. And life.
A lot that goes on in business also goes on in life.
Here's a quote from The Fifth Discipline:
"Learning any new language is difficult at first. But as you start to master the basics, it gets easier.
Research with young children has shown that many learn systems thinking remarkably quickly. It appears
that we have latent skills as systems thinkers that are undeveloped, even repressed by formal education
in linear thinking."
What is systems thinking?
Again, from that book:
"The essence of the discipline of systems thinking lies in a shift of mind:
*seeing interrelationships rather than linear cause-effect chains, and
*seeing processes of change rather than snapshots
Things aren't always straight-forward. Learning isn't. Life isn't.
