A resume should start with short but clear and open sentences. Your goal is to show that how much you understand about the job, why you love that job and how much experience you have gained when doing similar jobs. Then, why do not you put those in your resume and it in a professional way?
Focus on the most importance: A resume or a resume both requires focusing points. You should go deeply into the most important points about your qualification and knowledge about the job and the company. You may make bold or italic important points (if printing).
