It is incorrect to view your CV as a personal statement, a chronicle of your career, or any kind of self-expression. Yes, the majority of the information on any resume is devoted to your work history. However, write with the purpose to pique curiosity and convince the employer to call you. Your final result will be significantly different if you write with that objective in mind than if you write to inform or catalogue your employment history.
Most people create a resume because everyone is aware that you need one to find employment. They reluctantly draught their resume in order to fulfil this requirement. In the hierarchy of worldly pleasures, writing a résumé is only marginally superior to filing taxes.
