When you don't get into the classes that you would like to be in, use those times as opportunities to take other classes that interest you or may not align with your intended major at all. Remember as you go, that your major doesn't equal your career. I majored in business and then hopped into a corporate job out of college. I found that I didn't like the corporate world, and then by a random assortment of experiences and jobs I had (Orientation leader etc.), I decided to make a switch toward pursuing a career in counseling.
