It is refreshing when employees admit their errors, and view them as opportunities to learn. A much more admirable approach would be to own up to the fact the mistake was yours. Then, go a step further to explain your plan for both correcting and avoiding it in the future. Employees who accept responsibility demonstrate professional maturity and confidence. Your credibility will be higher if you are honest about your errors and strive to correct them.
Nothing is more impressive than an employee who goes the extra mile.
Big picture thinkers move ahead quickly by looking beyond the current task at hand. They don't wait for others to identify and pursue areas needing improvement. Enthusiastic employees who are not afraid to take risks find themselves noticed and rewarded. Those that simply serve their time won't get very far in a quality organization. Complacency is also evident by those who neglect to keep their skills up to date.
