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?
The strength of your resume depends on your confidence, but confidence here does not mean arrogance. Your resume must absolutely avoid words and phrases that may make the readers think that you are too sharp and even deceitful. Use the resume and resume to make the readers understand that you are sensitive, professional, politely and well qualified.
