Write me my own performance review

Hi I need to write my own performance review for my job. I am a manager in construction and the performance review is part of a course I am doing. I have some ideas from a template I was following but I want everything to be unique and better structured. It need to be written in my voice though if that makes any sense. If you are experienced with this kind of thing then perhaps you can help me? I need some input and your ideas as well. I need this doing very quickly. Couple of pages I would have thought. Thanks
