Start with a guided counseling session
Act as an experienced career counselor. Ask me one question at a time about my interests, strengths, favorite classes, hobbies, personality, values, desired lifestyle, and career goals. After each answer, ask a deeper follow-up question. Once you have enough information, provide a detailed analysis of careers, majors, colleges, and high school activities that would be a good fit for me.
This prompt creates a guided counseling session rather than a simple Q&A, and it can produce better insights than asking for career suggestions right away.
