Change is hard and slow. Bad habits are stubborn and take years/decades to form and in turn, inform.
That said, I do believe that there are certain transformative moments —that might be triggered by urgency, desperation or great longing — when we reach a dead end in our lives & take a Leap.
Here is a quote by Kafka (from his novel The Trial) that articulates this slippery truth:
From a certain point onward there is no longer any turning back. That is the point that must be reached.
Of course, this applies to nations as well as individuals, when enough becomes too much & one’s old way of living becomes impossible — hence, (r)Evolution!
