The posts above all give you good ideas. I changed my major several times before finding what I truly wanted to do. I knew I wanted to be a teacher which helped, but I started out in elementary ed which I found out was definitely not for me with all the little projects. I then switched to history at the secondary level which I liked, but when I visited the placement office, I realized that unless I was incredibly lucky or a coach as well, I would probably not find a job. So, I then added secondary level English as well as a minor in French. The point to all this is that you will find your way if you are willing to ask questions, visit the counseling department for inventory tests of your skills and interests, and be willing to consider other majors. I know no one I went to school with who didn't change majors at least once. Try to get some practice at what you think you want to do so that you don't finish your degree and then find out that you don't like it. Good luck.
It sounds like the best major for you when you start out will be that most popular of all majors - "UNDECIDED"! There's a very good reason why it's such a widely used major - there are an infinite number of possibilities, and part of your job at university will be exploring the options and finding the field which best matches your interests and abilities.
If this question comes from a place where you have no real feeling of how to even begin the search, you might consider contacting your guidance counselor at HS or someone in the Learning Center or equivalent at your university next fall and ask for some help doing self-evaluations and career assessment activities. These tools can help you to identify areas of particular interest and strength and then give you possible careers based on that information. Could help with finding a starting point...
I have to support the ideas of the posters above. If you are doing something you love it does not seem like a "job." I would suggest that you do not go into something which will make you rich. Go into something that will make you happy. Therefore, the best discipline is the one which will allow you to find happiness in your career path.
The best discipline you can study at the university is the one or ones that make you excited or interested in going to class and that also give you a vision of the rest of your life. As mentioned above, your working life is a very long one and the investment of time you make now can pay out long returns in both your financial and personal success as an adult.
As for self-discipline at the college level, students need to recognize the importance of a good education and seriously attend to the necessities that will help them succeed. Attending class regularly, completing assignments on time, and keeping up with the extensive reading and research demanded by most teachers are far more important than the outside social matters that tempt most students. As for the specific degree you pursue, it should be something that interests you and for which you will be competent upon completion.
Here -- look at this link. Look especially at the graphic towards the bottom. It tells you what kind of unemployment rates there are for people who major in various disciplines. It also tells how much money you are likely to make. Of course, university should not just be about how much money you can make, but you probably ought to take that into account.
The best discipline is the one that you love and feel that you will be interested and enthusiastic about for the rest off your life. Your career will be a big part of your life, and being happy with your choice of career is very important. A person who loves what he or she does will be successful. A person who chooses a career strictly for practical reasons is more likely to be unhappy, and an unhappy person is rarely successful. Look in the mirror and ask yourself what YOU think the best choice is. Good luck.
I'll make a pitch for the liberal arts, based partly on the kind of evidence cited in the very recent article below. Any classes that can help you learn HOW to learn, think critically and analytically, and express yourself clearly in writing and in speech will be helpful in the long run. Clear, logical writing is unfortunately pretty rare these days. Read as much as possible, whatever your chosen field.
Well, university is definitely supposed to prepare you for some basic life skills that will prove invaluable to you in later life. The biggest one of course is timekeeping and keeping to submission dates. However, obviously this could be improved upon. I used to be able to skip tutorials without being chased, and this is something that obviously should be picked up on.
