Subject: If you have decided upon a major, you need to address this question: How will the three acts of the mind help me in my studies as I learn my major, and how will they help me in the workplace once I have a job in my field?  
If you have not decided upon a major, you need to address this question: How will the three acts of the mind help me make a decision as to which major to pursue?  
In either case, address the subject using each act of the mind separately – understanding, judging and reasoning, then summarize the total effect that the three acts will have regarding which question you answer.  
In case anyone thinks that the three acts of the mind do not apply to your field, they do. Think it over. If you cannot understand how they do, please E-mail me and ask how they do. I can usually come up with whatever is necessary to help my students understand. 

my major is: Finance.
