Are you on the right road? Surely the leadership position fell on you not from heaven. In the sense that you were not seized by the sleeve and offered to lead. Even the most loving daddy in the world will not trust his business with a stupid and windy daughter. If you are at the head of a division or an entire organization, it means that you have already proved your professional level. Even if you have only one subordinate - nanny of your child, it says that your time is more expensive than the time Mary Poppins. First, write this fact into your asset. At the first stage, it will help you at least get rid of the uncertainty that you have the ability to become a real "Big Boss".
In a free style. You became a new young project manager and should know that a strong, bright, charismatic commander is a stereotype of a true leader. And your nature is far from stiff. Does this mean that it's written to you not to be a boss? In fact, it means only one thing: you will manage people in your own style. At least, at first. Over time, perhaps you will feel the need and, most importantly, the internal opportunity to adjust it. This will look much more organic than when the new young "Napoleon", shyly coughing, threateningly screams at the secretary. Looks ridiculous, and, whether you're even a sideman in the forehead, that's how you, the project manager, will be perceived - not seriously.
A new broom swings in a new way. A new broom is you, a new young, and even a project manager. And they are subordinates, through a word yearning for your predecessor. Do not be hasty to feel alien at this celebration of life. With the arrival of the commander in the team on the part of a wary attitude can not be avoided. But what exactly one can avoid is not to be the "new broom". Before the "new revenge", think about the fact that "Mr. Self-Perfection San Sanych" for a reason, probably, created the system as it exists today in the company. You, as a new young project manager, need to look closely and find out how the system works. During this time you will have time to understand that people are experiencing much more painless evolution than evolution.
Your strategy and tactics. The real commander (in this case, the project manager) is without a black horse, but there is no strategy. Perhaps, this is the only really necessary attribute of the commander. Do you imagine what result you want to achieve in a year, three, five years? And do you know how to competently break your plan into temporary stretches and intermediate goals? Hence, our "Suvorov in a skirt" also has tactical lessons. Now estimate the probability of victory. The first real success will give you weight in the eyes of subordinates.
A losing option. It will happen when, having occupied a new office, you, the new young project manager, decide to end your office gossip at once and even go to a common smoking room for these purposes. In this case, you will not even notice how you become a heroine of the underworld wars. After all, the most important thing is to involve the chief in the conflict and, thereby, to strike at his only emerging authority. It's not for you, is it?
