If you are an active participant in your career, meaning you take action to get outside of just your education and try volunteering, working a part-time job, joining student organizations, and get involved in other areas on campus, you will be well prepared to find your way into a career that you love after school is over.
Remember to take time to reflect on any new experiences you have as well, as this can help you learn about your likes and dislikes, and other work preferences for the future.
You've chosen a field with many opportunities, and you don't need to decide now exactly where you want to end up. The more exposure you can get to various occupations, the easier it may become for you to decide what you most would like to do. Have coffee with various people who work in the world of business and ask what they do and what they like about it.
I began in a very basic administrative position and was able to move into the travel management area where I worked, which gave me an opportunity to do a lot of business traveling around the world. Eventually I ended up at the same company doing employee training. Part of the process is building good relationships and being open to new possibilities.
With every good wish!
