First, make sure that you get as early a start as possible. When you are taking classes in marketing, remember that you should network as much as possible. Join any organization that will help you get the contacts that you need and remember that an internship will give you a lot of experience right off the bat. At the very least, it will show you what you need to understand about the way the industry works. Interning can also land you a job later on, when you graduate. Remember that more and more, interning is turning into a three month long interview. It might be the best opportunity that you have to make a good impression, so don't let it get away from you.
Also remember that you are going to be needed to be up on the trends that are important right now. At the moment, the two main key words that you are going to need to look into include sustainability and efficiency. The first has a great deal to do with going green, something that many companies are focusing on at the moment, while the second has to do with improving the company in the eyes of the people who it services. Unless you can get your work cheap and fast these days, no one wants it, and you need to make sure that your company can give you the results that you need. There are so many different options that you need to explore in this vein, so open your eyes.
Also keep in mind the fact that you cannot afford to be ignorant about the way that social networking works. More and more employers are moving their employee search online and there are so many resources online that it would be almost criminal to ignore them. Take a moment to really figure out what your options are going to be and to figure out what your needs are when it comes to being conversant with marketing on the Internet. This is something that can make a lot of difference in the long run and you will be in a better place to appreciate trends in this case.
There are many ways to succeed in marketing and with the right amount of information and determination, you certainly can. Take a moment to figure out what your success might look like and what you can do to get the results that you need.
