If you decide not to participate in any course in your life anymore, you might be making a mistake. Everybody has to learn new things all the time. You might need to participate in courses such as acls courses to elevate your career or to simply broaden your horizons. You might have bad memories from the time when you were a student. Attending courses can be a lot more enjoyable experience than being a college student. While full commitment is required from you when you are a student, you will never be asked to do a lot when you participate in a course.
