A quick question for college students about encouragment

[jason_t]

Suppose that you are taking a difficult course in your major field of study. The instructor hands back to you your first graded assignment with the following note.

Very sincerely,

Jason.

How would it make you feel? Is there something the instructor could write that would encourage you? How about if I put a [img]/images/graemlins/heart.gif[/img] at the end?
