From my lecturer
Once there was this professor, who embarked on a twenty year
research into tea leaves and tea making.
He travelled the world, and compile everything he can find out abt
tea leaves, from India to China, and each country's brewing
techniques
At the end, he compiled his research.
After that, someone told him that within the mountainous region of
his homeland, Japan, there is this wise old man who also know a lot
abt tea and can teach him more abt tea.
So this professor paid the old man a visit.
Once he met up, the first thing he told the old man is that he
believe he know all he can abt tea and tea making, how he travel
the world over, etc etc
All this while, the old man continue to pour tea into his teacup
for him. It quickly fill to the brim, overflows and wash up the
entire table
As the professor move away from the scalding tea, the old man
said.
"Ur mind is like this teacup. Its filled to the brim and refuse to
accept anymore knowledge. If u close ur mind to more things around
u, there is no more others can teach u"
