Nature delivers the greatest Zen masters in learning how to live in the now.
I was watching a turtle on the beach who spotted a juicy green leave of lettuce about 200 metres in the distance and he started moving.
After 45 minutes he still wasn’t there and I could see he was getting tired because he was moving even slower, so he rested for a while. Then he carried on. Bridging the last 50 meters or so, still took another 15 minutes. Finally he got there and I have never seen a turtle indulge in a piece of lettuce that much.
Even at the end of your strength, there’s still power within you. Find it, use it and you can achieve amazing things.
