Continue with your education and then get some experience so that you can get first hand knowledge on what it takes to be in the business industry.
Find a mentor in the business field who you can shadow and talk about current trends in your area. There are a lot of programs available for business leadership to work with college students to help them understand specific industries and market trends.
Every company, industry and market have their quirks. Taking part in a shadowing program with local leaders gives you an insight into their industry as well as a contact when you start looking for employment.
First, make sure that you get great grades in all the courses that you take. Second, take the help of your professors and make sure that you complete all your assignments in all the classes before the deadline. Third, get a third or final year student to serve as your mentor. This student should have excelled in his or her studies, is a leader in your college, and has the time to serve as your mentor. Fourth, improve your communication skills. This involves improving your writing skills - email writing, report writing, etc. Fifth, start building good networks in the business community. Last but not the least, be respectful, polite and honest with all the folks you deal with: professors, fellow students and peers, staff, etc.
This is a general question. First, what type of Business to you like?
I recommend as early as the summer of your sophomore year (after completing your second year) line up an internship. Your Professors/Department Heads can assist as can the Career Development office ("job placement" or some other catchy name they have for it).
I would focus on making your studies as effective as possible ,i.e. communication skills,( presentation abilities, writing and speaking in front of groups, computer skills,( excel, word, pivot tables, power point) team work skills( working with others, leading and following, conflict resolution).
I would also think about volunteering. This is an excellent way to gain experience and gain assess to someone in the business field. I would also begin networking join Linked in. The more people you can become exposed to the better.
Find someone you consider successful within your definition.
Business is a highly practical and useful thing to study in school, but there are about as many "paths" to take after school as there are people. While you are going through your business classes, I would encourage you to think about what aspect of business interests you the most and best utilizes your skills, e.g. accounting, marketing, finance, organizational leadership, entrepreneurship, non-profits, etc. This will help to focus your goals a bit more. I would also encourage you to look into internships or job-shadowing or other activities you could participate in while you're in school. This will not only help you further decide on a future career, but also give you real-world experience to help build your resume experience.
