These two types of teacher exists in my school
One, a teacher that gives all he got, without looking at the students' limit
Two, a teacher that teaches what he knows to the students' limit
They are good friends, yet have a contrary paradigm
One day, both of them joined a camp for teachers
And one of the preacher told them a phrase

Enough is enough

I was hoping teachers got the message well, especially the type one teacher
I know it is very good to teach what you've got
But sometimes, teachers have to know when to stop
It is stressing for students to be taught more than we could absorb
If you really want to teach more, my suggestion is make a club or something :D
Where you can really teach all you want, all you've got
To students who have genuine interest
That will hear and study all your teaching
