Most people choose a career partly for the financial security it can provide or the enhanced standard of living. These choices are completely valid, but people often find that if they stay in a job that pays well but doesn't provide anything else, they end up disappointed and frustrated. They also need work that is enjoyable and challenging. Be careful that you don't get used to a high paying job and a pricey standard of living which then rules out career choices that would be more satisfying.
Many people choose careers for the rewards they bring.
In some job situations you may be recognized and admired for your talents and achievements. These rewards can be important in helping you to develop your sense of self-worth. However, a job must provide more than just these external rewards or you will probably end up feeling bored or restless. It is important to find a job that is intrinsically satisfying as well as rewarding. You want the work to be enjoyable and interesting for its own sake.
