Change happens. That's a given.
Yet change has variability in its timelines.
Conditions Change. Conditions can change very quickly. Weather conditions can change in a heartbeat. A protest can turn into a riot almost instantly.
People Change. People usually change more slowly. Sometimes a person will change after a traumatic experience, or as result of illness, or in the wake of a religious experience, or concluding that they've been very wrong.
Systems Change. The slowest change clock of all is that which alters a system. This is the stuff of culture. The IRS won't change very quickly, if at all. An ideology (political or religious) will only budge at a snails pace. Dogma is an extremely slow learner.
For those of us interested in a better tomorrow, we'll have to commit long-term to tinkering with System Change, because People Change and Conditions Change almost always occur downstream.
In all areas where humans are involved, it's the habits that matter.
