One of the key abilities of successful people thinking in a project perspective is effective communication. Communicating effectively means that we own the strategies, which are required for us to find the common tune with different types of people. In order to successfully cooperate with people, who have a difficult personality, apart from taking the generic principles into consideration, we may also have to change our own communication, depending on the nature of the other person. Effective communication is half the road towards success, and those who think and live with awareness are capable of finding the common tune with anyone, in any situation of life. For the sake of results and goals, these people are capable of placing themselves in the background, if the situation desires them to, or are capable of making their voices louder, becoming a bit more aggressive when the need arises to do so. What’s important is for us to realise the style, strengths, weaknesses of our discussion partners, and choose our own styles in light of these.
