Studies have shown that only half of incoming college freshmen know what they want to do when they start college. It used to be required that you declare a major when you start your first year of college but, over the years, there has been a decline in that requirement.
Many colleges and schools in the United States will allow students to start school without declaring a major, and a large number of schools now give students the opportunity to ‘build their own.’
There are hundreds of areas of study to choose from. If you have passion in a certain area and would like to build a career on that passion, there is a strong chance that there is a college out there that offers the program you need to make that into a reality. Even if it is a little out there.
