The ideal mind of the lawyer is the mind that easily understands and masters all the provisions of all laws and knows how to apply it in all circumstances. It is very logical and philosophical that can argue in every point of view of the cases and provisions. It does not make any logical errors when it comes to law. It is very critical in evidences and may reverse disadvantageous cases.
The ideal effort of law student is briefly defined as reading, reading, reading and reading a lot of cases, and memorizing, memorizing, memorizing and memorizing all the provisions of laws. Another thing is patience. The 80 percent of time should be allocated in reading and memorizing.
A lawyer can survive just with the "mind of the lawyer" while a law student should have both the "mind of a lawyer" and the "effort of a law student." But, a person cannot be a lawyer if s/he did not became a law student.
For a law student, the "mind of a lawyer" and the "effort of a law student" are essential and one reason is the current law curriculum and teaching style. I'll give this example when one time I was called in the recitation and asked about the details of a case which I missed to read. Even though I'm confident that I know all the provisions of the laws needed of the topic, I failed the recitation for just missing to read that one case.
On the other hand, the mind of a lawyer is important because even though a law student memorizes all the provisions of law and the details of the cases assigned, without it, that student still can't apply those that s/he memorized to more complicated and challenging case. All s/he knows is just the one verbally written on the books and the cases.
The mind of a lawyer can be obtained in born or practice. But of course, to obtain it by practice is not an easy task while those who obtained it in born are just lucky. I don't know exact formula on how to obtain it by practice.
In the case of the effort of a law student, all people have the opportunity of doing it. The only indicator of this is the laziness and the industriousness of a person. Some people find it easy and most find it hard. It needs dedication and motivation.
