Practicing the Power of Now

I'm curious about what inspired the emphasis on living in the present as the key to personal transformation. Was there a particular experience or insight that sparked this approach?

Some of the mindfulness practices felt simple but hard to maintain amidst daily stress. How have others incorporated these teachings into busy routines?

It's been described as life-changing for many, but I'm wondering what aspects of Tolle's message strike a chord on such a personal level for different people.
