I don't know which group to select. I am stuck between pre-medical or business. How do I choose which as both I am interested in?

Well, if you're equally passionate about something, make a chart of pro's and con's. Start thinking about other things concerning the two groups. Ask questions like: 1. Which will have more benefits long-term? 2. Which will be cheaper and/or easier to pay off? 3. Which one suits my personality better? 4. Which one has more diverse career paths/more preferable career paths? 5. Which one can you make more money from and at which times? 6. How much work will you want to put in? 7. How much money will you hope to end up making and how long do you want it to take? 8. Where do I see myself in the future(excluding career wise)? Which career can fit with this future better? And so on and so forth. I used to be just as conflicted, choosing between psychology and teaching and literature, but I eventually chose to focus on psychology due to me already knowing a lot more about it, my personality is more suitable, and it's more of a stable job. Although I still plan to do the others, through deep thinking I came to the conclusion to stick with that. So just make sure you think thoroughly and deeply about your decision, and it might help to write it out!
