Umysł zen, umysł początkującego

Suzuki's approachable style makes Zen accessible, but I'm curious what motivated him to present these teachings in this format.

Embracing a beginner's outlook can be so counterintuitive, especially when I catch myself overthinking. How have others tried to practice this in daily life?

The teachings on letting go seem so relevant today, but I wonder how easily they can be integrated into a busy, modern lifestyle.
