As has been indicated above, the word resume comes from the French word resume meaning "summary". Leonardo da Vinci is credited with the first resume though his "resume" takes the form of a letter written about 1481–1482 to a potential employer, Ludovico Sforza. For the next roughly 450 years, the resume continued to be a mere description of a person, and included their abilities and past employment. In the early 1900s, resumes listed things like weight, height, marital status, and religion. It was not until 1950 that the resume evolved into something more than words written on scraps of paper. By then, resumes were considered very much mandatory, and started to include things like personal interests and hobbies. It was not until the 1970s, the beginning of the digital age, that resumes took on a more professional look in terms of presentation and content.
Those questions represent the most common reasons why someone would begin to look at their resume and decide if it needs to be updated. What most people discover over time is that their resume should always be update-to-date as job changes can occur suddenly and without any prior warning.
Many people would love to get a better job. And most of these same people have the proper training and skills to achieve this goal. Unfortunately, so many job hunters have very poor communication skills. They are unable to clearly tell potential employers about their job qualifications. In short, they do not have good job seeking skills. In many cases, this prevents them from getting a high paying job that they could easily do. Often, the job will go to someone who is less skilled but who has written a eye-catching resume.
So the exact purpose of a resume is to summarize your experience, knowledge, and accomplishments. Therefore, you must avoid being too wordy. Say exactly what you mean in the least number of words possible. The length of your resume is important. Resumes should be from 1 to 3 pages long. Don't be tempted to make your resume longer than 3 pages, even if you have a lot to tell. Remember, a resume is supposed to be a summary. A resume that is too long simply will bore the reader.
