The resume: gateway to your future, toll booth on the road to success, and many more interesting metaphors. Whichever way you look at it, your resume is the key to landing a great job. However, even though this is a widely recognized fact, I still see resumes come across my desk with glaring errors and obvious problems. With this in mind, I've compiled a list of the biggest five resume mistakes that I see which are easily preventable.

The Internet is not simply a place for big businesses to get bigger or for new ideas to be rewarded with huge bonuses. There are numerous ways in which the everyday person can get in on the act and make their own small business.
