Peaceful warrior is very focused on enjoying the journey, and living one's passion.
Why?
Because once you've attained that goal... what do you do? You cease trying to attain that goal. What happens? You backslide back to the previous weight.
What if instead, our goal was to develop the daily habits which would result in maintaining a healthy weight?
Peaceful warrior is about taking your eyes off the prize, and putting them into the joyous process that will result in that prize.
Favorite line: "The rock."
Note: The books that this movie are based on are also very interesting, and very different.
