What moabos people Successน bte s Who do you think is the most successful? Who do you think is the least Successful? In order to answer these questions, we first need to define success. Everyone has a different definition. Many of us place great value on performance, on achievements, or on Others goals. SUCSS reaching various associate success with material goods, measuring it by how much one can acquire. Others measure success by how much they can contribute to the well-being of their families, or to the community and society in general There are many other definitions, but mostly success is associated with becoming rich, famous, and respected at work. Yet, it doesnt have to be that way. Being successful could mean simply being satisfied with oneself and one's career. For many people, a successful person is someone who feels that his or her work and life in general offer an exceptionally high degree of satisfactions. But how does one get from here to there? How does one reach this feeling of satisfaction with life and career? It seems that successful people consistently do two things: * They use their natural abilities in their work. * They set career and life goals. In other words, successfuนl people choose careers where they can use their natural abilities, or do what comes naturally to them. For example, successful teachers are people who instinctively know how to help people learn, and the best doctors are those who know how to listen to people. Successful people know where they are starting from, and what direction they want to give their lives and careers, even if it is something as simple and wonderful as raising a happy family. What are your natural abilities? What are your career and life goals? If you can answer these questions, you are on your way to having a Successful career and life.
