Just as you need to write your CV for every organisation and role you apply for, so too will you need to make your career objective differs for every application. Inserting something generic will not succeed in making yours the most compelling one, nor will it even be suitable for the application in some cases. 

Writing a career objective for each role requires you to do your research. Read about the organisation, their history, size, values, mission statement and people. Speak to existing employees if you can. Read articles and forums and chat to friends in the industry. Find out, where possible, what sort of employees the organisation wants, and why. All this information will help ensure yours is specific and relevant to you, the organisation you are seeking to work at and the employer or team assessing your application.
