1."I am the best candidate for the job."

　　At the resume stage, this is an irresponsible and presumptuous thing to say. Obviously, you don't know who else is applying for the job or how your qualifications stack up. Say instead, "I am very interested and believe I'm qualified for the job." Then, use the next sentence of your resume or cover letter to say how.

　　2."I have a proven track record of success."

　　Apart from its 10-out-of-10 rating on the Legendary Clich scale, this sentence makes no sense. What other kind of track record is there? There's no such thing as an unproven track record. The "success" bit on the end only lowers the perceived IQ of the writer. Replace this boilerplate phrase with a story about something specific you did to help your last employer.

　　3. "I left this job because of disagreements with management."

　　I would never advise you to lie on a resume, but the problems-with-management message stands out like a neon sign on a resume and spells trouble. Instead say, "A shift in organizational priorities made this role less of a fit for me over time" or, "I'd learned a ton at that job, but it was time to go."

　　4."I am an out-of-the-box thinker."

　　The thing about true out-of-the-box thinkers is they'd never use this clich. Don't tell us that you're creative. Give us an example of your creativity, like "I revamped the Accounts Payable process and saved our company $1M."
