I have observed that there are broadly 2 types of students.
One type (Type A) is more concerned about being right. These guys want to prove it to me and others that they are smart and intelligent. They are cut off from inputs. They are less curious about their project, but more concerned about their image.
The other type (Type B) of people are genuinely curious about their craft. They are constantly looking to learn. They are more concerned about the work.
Sometimes I myself am student A and sometimes I am student B.
Let all of us aspire to be student B more often.
