Learning is like sailing against the current. If you don't advance, you will retreat.
There is no doubt about being a student, and progress can only be made if there is doubt.
Those who don't know enough are eager to learn, and those who ask questions are complacent.
A person's real knowledge lies in knowing what he knows and what he doesn't know.
People who are keen on learning learn from others and make up for their own shortcomings.
