Choosing a Job Title for Yourself

How important is choosing the right job title for what you do? Let’s say you are in a company and they tell you what your general duties are, and then they dont really give you a title. Therefore, it is upto you to come up with one to put on your resume for the future. How should one go about doing this? Are there some job titles that are better to use than others? If anyone knows of any resources or has any suggestions regarding this, I would appreciate it. Thank you.

mostly on the career websites there are some generic Job titles and their description as to what they do...you might want to check them out and then decide because the generic tittles are the ones that companies are looking for most of the time......
