It's fantastic you are being so forward-thinking. I would advise that you take the time and enjoy college. Your life is about to change in a great way. College is a time for self-discovery, determining what you want, building lasting friendships and relationships and having life experiences that you will always remember. As you start approaching your final years of college you will have a better handle on what sort of profession you will be pursuing. Once this is in place, work with your academic adviser to explore what sorts of internships, jobs or other sorts of work may be available to you following college. Apply as much as you can while you are in your final year to assist in a transition plan.
Once I had an idea I wanted to continue to pursue a career in business, I applied to several firms in my final semester, received a job and it allowed to me to set up a transition plan to move. You will be just fine, enjoy these next years.
