College is not for everybody. Surely, having a degree doesn't guarantee you a pass into the middle class, but it does serve as a nice trophy in the work force. However, the road to obtaining a degree isn't as easy as I thought and I've learned that the hard way. So, I will bluntly share eight brutal lessons I've experienced about the world outside of college, during my career in college.

Your friend today will probably be your distant rival tomorrow.

College can be a fun experience when you make friends easily. Ever had one of those classes where you meet someone and automatically click with them? You guys talk back and forth during lecture, and you feel as though that person will be your best friend for life? Well you better think again because as soon as final's week rolls around, that same friend will quickly become your competitor in the blink of an eye. And should you perform better then them on an exam, forget it! You'd best believe that your 'friendship' with them has ended. That bond they had with you during the start of the semester will now be shrouded with envy, and the need to do better than you will fuel them.

College professors will lecture you on the importance of getting a job, but wont tell you how to get one.

Although it is true that performing well in academics looks good on your resume, it isn't necessarily useful in teaching you the skills of getting a job outside of college. Such skills include: how to properly communicate with employers, how to conduct yourself during an interview, how to hold a professional posture, how to network, and so forth. Instead of being taught in lecture halls, these skills are essentially acquired through self-experience. This means that if you've been getting your nose stuck in a text book all semester, then you happen to land a job, you will probably humiliate yourself during your first professional interview. Don't feel too bad about this, but rather take it as a learning experience. In college, you will screw up a lot, but don't give up. The ability to keep going is what will keep you afloat all throughout the years of school. Trust me, you will get better with time.

You will meet people who are richer, smarter, and more successful than you who probably work less hard than you

For some people, this can be positive, but for others, it can be destroy your mental health. Let's say you've studied five hours for an exam, and score a B-, and the person next to you did zero work and scored an A, expect your blood to boil. Unfortunately, these types of people will always exist in college and avoiding them is inevitable. I've gone through a series of students who never study and still perform well and chances are you will too. Encountering these people might cause you to feel insecure, because you will constantly compare yourself to other students, or even lower your standards for yourself. That's why it is extremely important to remain headstrong in these situations and focus on yourself instead of other students. Don't fall into the trap of dwelling on the success of others no matter how tempting it can be. Remind yourself that those people have closed doors in their lives to which you don't know about. Perhaps you have a skill that hey lack, and you could wind up using that to your advantage.

You will become isolated from loved ones

This is a common one that I've noticed time and time again in the lives of college students. If you're a student, chances are that isn't your only occupation. You will probably be working a part-time/full-time job, or even two! This means that because your demand for money and schoolwork is high, you utilize most of your time working and studying. That leaves you will very little time to spend with family and friends, especially during exam period. Chances are you will only see your family an friends on holidays, and to cope you will have to fix a schedule indicating when you can spend time with loved ones. Relationships will be extremely difficult to manage, especially if both you and your partner operate on opposite schedules. Hence, college will cause you to feel isolated, lonely, depressed, and incomplete. The good news is that all the hard work and sacrifices pay off in the long-run, and eventually, you develop a plan for your career goals.

The material you learn aside from your major's is useless in the professional world

Sadly, some colleges enforce that you to take a set of General Requirement courses, also known as "Gen-Ed" classes in various subjects. Although this can be good, because it allows you to explore many fields, and basically choose what you like for your major, it's also bad for three reasons. First, it forces you to follow a curriculum that sets you apart from your major courses. For example, if you know you want to major in accounting, but you're forced to take a psychology 101 course in order to graduate, chances are you'll be distracted and you wont give accounting your hundred percent effort. Second, taking elective classes is time-consuming and unnecessary for people who already have their 5-10 year plan set up. The third reason in which Gen-ed classes are bad is because it consumes your brain with knowledge that is useless in the long-run. For example, if you're focused on getting a degree in Forensic Psychology, but you're forced to take MUSIC 105, you're pretty much screwed because what good is that knowledge about Music in the field of Forensic Psych? Besides, you will end up discarding half, if not, all your MUSIC 105 notes by the end of that semester. But until you pass MUSIC 105, you will still have to work hard, spend a couple of hundred dollars on MUSIC 105 textbooks, and attend lectures that will enable you to continue pursuing your Forensic Psych degree.

You will learn more from Google than your college professors

Often times, while working on a research paper, or thing a quiz online, you will find yourself getting distracted. You will minimize your Microsoft Word document, or close out your Google Docs tab, and open a new one. You will visit Google, and search up something that you have questions about. Indeed, two hours will have passed, and there you are, still Googling the name of the famous tourist location, or another one of Donald Trump's immigration policies. All in all, Google will be your entity, and you will learn much more from that search engine than you do in all your lectures. Part of the reason for that is because Google is a worldwide monopolized search engine that is designed to satisfy your curiosity and intellectual needs. I mean who needs professors when you've got a free website like Google answering all your questions, right?

If you're aiming for post-graduate education, you will become grade obsessed

Believe it or not you will. Your professors and colleagues will tell you the cliche that understanding course material is more productive than focusing on grades. However, you will soon discover that this is false; and having that mentality will get you close to nowhere. If you've never been the competitive type, best believe that after four or so years of college, you will become the most superficial, and competitive nutjob about your grades. Part of the reason for this is because many post-graduate schools require a minimum GPA and/or Standardized Test score for admission. If your GPA fails to meet the required GPA for Harvard Business School, your dream school since birth, having even a slightly lower GPA can reduce your chances of getting accepted. As a result, you will gradually be forced into a grade-obsessed mindset, and nagging your professors for a higher grade will become a pivotal part of your agenda.

Opportunities will reject you

This is the hardest pill to swallow, but it will happen. You will get rejected. Multiple times. By schools, internships, employers, scholarships, fellowships, etc. And truth be told, it will sting! However, the key aspect here is that you do not let yourself be defined by the amount of times you get rejected. I know this can be a hard task, especially when you've worked extremely hard on that resume, or if you spoke the best during that interview, and you feel like you've only been lead on to get hired. Chances are the person interviewing you just didn't like you. Or perhaps he/she preferred the girl next to you for reasons you'll never know about. It could be secretive discrimination, a small miscommunication, your tie was probably wrinkled, or maybe it was some other personal preference that had nothing to do with you. Whatever the case may be, don't give up. Simply take a few days to grieve, think it over, and figure out new ways to improve your performance. But don't take too much time dwelling on what could have been. Eventually, you're going to have to move on.
