Use all the authority you have now. It shouldn’t be difficult at all for you. You’re in a good phase where your confidence is concerned, and you have already had a taste of power. Build on your reputation by making the tough decisions. Don’t pull any power trips. Deliver your demands in the form of a request. Think the best of the people you’re in charge of and you’ll send a supportive and respectful message. But don’t back down from what you need.
