A leader is someone who is capable of developing a solution for a given problem and be able to do whatever is necessary to implement it. He must be able to act with courage and with the company values in mind. He must always have a proactive, optimistic attitude but should also be pragmatic in terms of risks and plans. He should genuinely believe and always make sure that his personal interest is in line with that of the company. He should be able to motivate people and have enough people skills as to make others follow him not by the means of force but by good will. He should be able to convince people to trust and follow him and not let them down. The role of a leader (formal or informal) should always be a positive one – he is the one who makes things happen.
