There is no universally preferred format. Many job seekers spend days perfecting their resumes, agonizing over whether to use a chronological format or a functional one. This question may be akin to figuring how many angels will fit on the head of a pin. There is no one perfect resume to suit every employer's needs. But there is a perfect resume for a specific opportunity. If you are going to focus on perfection, do it on an individual, rather than a global basis.

No one can help you in holding a good job except Old Man You.

Learn to think in positive affirmations. Affirmations are any statements you make. Too often we think in negative affirmations. Negative affirmations only create more of what you say you don't want. Saying, I hate my job, will get you nowhere. Declaring, I now accept a wonderful new job, will open the channels in your consciousness to create that.
Louise Hay
