You're a perfectionist when it comes to work, and willing to do whatever it takes to win. But make sure you aren't doing these...
Working for more than six months with no personal time off. Even just a day off to do nothing but watch TV at home can recharge you. Better yet, make sure you take one significant vacation once per year. Don't save all your personal days for later... live more in the moment. Your moment.
Doing all the work by yourself. It's OK to ask for help. In fact, refusing to may look bad, hold up deadlines, reduce your productivity and increase your stress, make you seem unrelenting and disapproving of others' work... the list of no-nos goes on.
