The word "résumé" originates from the French, and means "to summarize." Damn French. Because of their stupid word, you now have to condense your entire lifetime onto one piece of paper, with the desperate hope that someone who reads it will instantly know what a great person you are and give you a high-paying job.
But you, my friend, are completely misguided if you think that's what your résumé will get you. The purpose of your résumé is not to get you a job. "What?!" you say. "Years of classical conditioning have instructed me that if I write a good résumé, I'll get a good job!" Sorry, but you've been had. The purpose of a résumé is to get an interview, not a job. Once you get in the door, it's your winning personality and discussion of your lifetime of experiences that will get you the job. You could have the most brilliant résumé in the world, but if you walk into an interview and do nothing but drool on yourself, that résumé will be worthless (unless the job consists of massive drooling, or you are an actor portraying a two-year-old). But drool no more, for today you will learn how to put together the perfect résumé: one that will play up your experience, play down your liabilities and at least improve your chances at eventually acquiring your dream cubicle.
One footnote: We will be working under the assumption that you are either still in, or have recently graduated from, college. If you've been out in the real world (or sleeping on your mom's couch) for more than a couple of years, this all still applies to you. The only main difference is that you'll have to talk more about your work experience, whereas recent college grads can add stuff like school activities to their résumés.
