College is a learning experience. Some people will graduate in four years without any problem but you do not have to be that person. Look at me, I was at one school doing one major and then took a semester and changed schools and majors. I am happier in my new major but I will not be graduating in that four year period and I am perfectly OK with that.
Graduation is important, but don't ruin your college experience by struggling to graduate in time.
It is not worth it. College is a time to discover yourself and become the person you want to be after graduation. Take the time and discover who you are. Go to parties (but do not let your grades suffer from over-partying), go be in clubs, go to football games or whatever thing you are into, and go out and have fun by being you.
College is stressful so sometimes you have to take the minimum load. That is OK!! Do not push yourself so hard because you think you have to take 15-18 credits each semester. You can take that 12 credits a semester if you want. Will you graduate in four years if you do that? Well, no, but you won't hate college every single day for it.
College is supposed to be fun, so let it be fun. Let yourself discover who you are. Because I took that semester off, I now know I want to be an accountant instead of a physical therapist. Because I took that semester off, not only did I see I needed to be in college and have a degree but that Troy is the right school for me. I will be graduating a year later than I am supposed to be, but that is a year of being involved in the community while also being involved in my school.
