My advice is to do a double major. Select one major that is personally satisfying to you. College should be a fun experience filled with personal growth. Also select a major that is purely marketable and which will prepare you for economic realities after you graduate. Try to pick majors that cross paths and compliment eachother, as you will be building critical thinking skill sets in the long run too.
For example, many people combine double majors in foreign language with a business degree. This is great if you want to work in business and travel abroad. The two together are more valuable than each one separately, and will help make your resume more unique among the millions of other college grads.
Another example, do a double major in environmental science and also philosophy. You will be prepared economically if you stick with just an undergrad, but you will also get some excellent preparation for graduate school in either law, engineering, or environmental protection. In this case, you will gain an excellent technical background (which tends to hold humanities majors back in the workforce) but you will also gain excellent written and verbal analytical skills (the lack of which tends to keep engineers and scientists from reaching management positions later in life.) This last paragraph is a personal reflection on my own experience.
When selecting your majors, ask yourself whether or not you see graduate school in your future. If you don't want to do grad school, you need to weigh your decisions more on the economic side- finish school and support yourself with less education. If you are going to graduate school, then you can advance in fields that that truly require advanced education, like psychology.
Also, if things change for you after college, if you don't get accepted to grad school or if you change your mind about your career path, a double major will give you more to fall back on and help you change course. A double major might mean you spend 5 years in college instead of 4, but in the long run that extra year is really insignificant.
