Grad School vs. Nursing School

Hi guess I have a question..... I was kind of in a bind while trying to choose between going to Grad school and majoring in Public Service or going to Nursing school when all of a sudden I heard this "voice" speak to me && say "You really don't want to go to grad school and major in that." And then I asked well what about nursing school then the "voice" spoke again and said "Just because you get in nursing school doesn't mean that you're going to pass the test." I know this might sound crazy but I really want to know anyone's thoughts as to what do you think these statements means to you. Thanks in advanced........
