Bringing Large Scale Change

Here is a good quote from Kent Beck on bringing large scale changes to the organizatio:

When I am in a situation where I want to change my environment, I try to
remember that I can only change myself. However, as soon as I change myself
I also change the way I relate to those around me, and that changes my
environment. That's how large-scale change starts, with one person choosing
to relate to the world differently and having that change spread.
