From the book "The Best Networker in the World" from John M. Fogg I read. Not for trading but learning, the starting point for all traders:
“In Japan, many years ago, it was the tradition among Buddhist monks to
travel from monastery to monastery, seeking the teaching of the masters.
As was the custom, the master would serve his guest tea and they would
“One young monk was a particularly outstanding student. In fact, he was so
exceptional, he had made a bit of a career out of showing up lesser masters
with his skill and tremendous intelligence.
“One day, he called at a very famous monastery attached to one of the
most sacred temples in all Japan. The master there was old and most wise.
The young man begged an audience with the master, in hopes of being
accepted as his pupil, to live and study with the great man.
“The young man – whose reputation had preceded him – was ushered into
the master’s chambers immediately. This was most unusual, and the young
monk was greatly flattered.
“The master entered and they bowed to each other. They sat across a low
table on the tatami mat floor and talked.
“The young man told the master of his journeys, of the teaching he had
heard, of the monks he had ‘bested’ in his search for Truth. It was a most
impressive tale. The master listened intently and acknowledged the young
monk many times for his wit and intelligence.
“A teapot and cups were brought in, and the master began pouring tea for
them both. The young man addressed the Master: ‘I wish to remain here
and study with you, for I sense that here, unlike with the others, there is
much you have to offer me . . .’
“And all of a sudden, the young monk cried out in pain and alarm, jumping
up from his place on the floor, shaking his robes and dancing about. The
scalding hot tea had spilled all over his lap!
“The master sat calmly and continued pouring tea – which was overflowing
the student’s small cup and spilling out over the table onto the strawmatted
floor where the young man had been sitting.
“'‘What are you doing!?!’ the young monk demanded. ‘I have been burned!
Stop pouring! The cup is overflowing!’
“'‘Go away from me, young man,’ the master said. ‘I have nothing to teach
you. Your cup is too full . . . overflowing with all that you know and all that
you think you don’t know. Come back to me when your cup is empty and
you are ready to receive what I have to give.’'”
