I understand why many students today have difficulty choosing a major/career path. There are so many options!
Do you have a sense of what would be best for her? Sometimes parents know or have a very good direction. Given that she is a junior you are talking about 4 quick semesters. In no time, she will be done with college but the fact is, you have to get her there and it sounds like finishing in 4 years is important to you. This will sound strange and out of vogue but maybe you need to narrow her choices down for her and strongly advise her. Some people just can’t make decisions no matter how much clarification and processing they go through. Is your daughter one of these people right now? I’ve seen so many people who just need to jump into something. Anything. Chances are as parents, you know what would be a good fit for her and a good choice given the impending job market ahead.
Given that your daughter is so bright, my guess is she will graduate, perhaps work and then go to graduate school at some point. For now, just finish that undergraduate degree. She might be looking for very strong urging from you on a major choice because she just can’t choose. Maybe when she will have a more clear picture for the next leg of her education when/if she decides to attend graduate school.
