I believe that self evaluation is extremely important when it comes to grown as a professional in the workplace. If you don't take the time to sit and reflect on what you have done/accomplished, acknowledge your successes but most importantly, recognize what mistakes were made so that they could be corrected in the future. Modeling one that follows proper ethics, following policy and rules, being respectful to others or even being the one that others can follow is great practice to ensure an efficient and professional workplace.
