Are You a Successful Leader？
1Almost nothing we do in this world is done in isolation. At work or at play， you'II find yourself in groups， working with other people： your team at work， a meeting with colleagues， your family， a holiday with friends， a group of students working together， a day out walking in the mountains， a group of neighbours wanting to make changes. It is now recognised that being able to work successfully with other- people is one of the major keys to success， partly because we need to do it so often.
2In almost every situation where you're in a group， you will need a skilled leader. All groups need leaders and all successful groups have good leaders： Groups without leaders or with weak leaders almost always break down. Members of a leaderless group often begin to feel dissatistled and frustrated. -llme is wasted and the tasks are not achieved.There are often arguments and tensions between people as there is nobody to keep the goals clear. Some personalities dominate and others disappear. Often group members begin not to come to meetings in order to avoid more disharmony.
3 Some people are natural leaders. The celebrity chef， Antonio Carluccio says， "True leaders are born and you can spot them'in kitchens." They're people who combine
toughness， fairness and humour. Although a lot of people agree that there are some natural-born leaders， most people now recognise that leadership can also be taught. Our professional and experienced staff can train almost anyone how to be a successfulleader Good leaders don't make people do things in a bossy， controlling way. You can learn how
to involve everyone， encouraging the whole group to work towards a common goal.
4 Our training courses use activities and techniques to develop a range of qualities which are necessary to be a good leader. Self-confidence is vital for you to overcome your own fears about being a leader. Successful leaders also need to be calm and intelligent. They need to be able to work out good strategies and make sound judgments under pressure. Lastly， and probably most importantly， good leaders need to be sensitive， sociable and be able to get on with a wide range of people. Good leadersV；ip is essentially the ability to influence others and good leaders allow all members of the group to contribute.
