One of them comes from our earliest years.

Five Things Nobody Told Me about College

As I type this , I am in my university dorm room. A year ago, when I was awaiting to hear the results of my college applications, I often went to websites for some type of insider look on what college would be like. However, there’s only so much that prep books, websites, and older friends can teach. Here are the top 5things nobody told me about college:

【1】

Nobody entering a university knows exactly what they want to study. If they tell you otherwise, they’re lying and will probably change what they want to purse within the first quarter of attendance . During my first quarter at University of California, Riverside (UCR),I thought that I wanted to study Political Science with its focus on International Affairs, so that’s what I applied for. However, once I worked with statewide and local government, I realized that a better fit for me would be Public Policy, and now I am in the process of changing my area.

【2】

In college, there are so many good chances for you to meet your expectations. However, there is a very important difference between wanting to do something and applying for something. In order for you to take advantage of the conferences, research, internships ,and fellowships that your university offers, apply! Step into your academic advisor’s office, introduce yourself, and begin making the valuable connections that are necessary to help during the rest of your college career. Great things happen when you step out of your comfort zone, and you would be surprised on how many chances exist if you just ask.

【3】

College is where you meet your birdesmaids, neighbors, and potential bosses. The relationships you develop now will probably be linked to the ones you value later, so be wise about the people who you invest yourself in . You are only one person, and you do not have time to waste on people who would rather cause drama or mess up with your purpose. Surround yourself with uplifting individuals who challenge you to be better while loving you for who you are, and be patient to the people who are the complete opposite of that description.

【4】

As a first-year, I was afraid to make any noise towards campus issues that I noticed. It was not until I became involved in student government that I gained the confidence to handle projects that I created with the help of ASUCR Office of the President. During my first quarter, I spoke directly to the Chancellor, asking him for support towards my initiavives, met with the Vive Chancellors, and coorerated with my teaching assistances to begin my undergraduate research protect. Nothing good will happen when you are silent.

【5】

At my high school, there were about only four active club and organizations that students could be a part of. Imagine my surprise when I stepped foot onto UCR’s campus, where over 400 organizations exist, ranging from political organizations to karate club. You are not paying all or your tuition(学费)to merely go to class, study,pass tests and graduate. Make something worthy out of your experience. Create that you will want to tell your grandchildren one day. It all begins here, by signing up to join an organization.
