||From the past researches on career success, personal characteristics, activeness and IQ were main factors to anticipate whether or not an employee would create a successful career. But in the process of a person's career, social support also plays a significant role that shouldn't be neglected. Talking about a person that has a successful career, we are easily able to associate with a white-collar manager who acquired high diploma and takes an important position at a famous enterprise. Or, it also occurs to us that someone owns a specific expertise in the field to be well paid. However, an insurance company or a real estate agency does not set up high entrance requirements, and those chosen candidates can later become an insurance agent or a real estate agent without being extraordinarily intelligent nor acquiring great diploma. Although these two industries have a high turnover of staff, those who stay and consistently create good sales performance are known to be greatly rewarded.|
Duckworth (2007), who emphasized the importance of “Grit”, indicated that a person's success is mainly from the lasting passion and perseverance towards his or her goal. In the past, comparatively few scholars made a research on the connection among “Grit”, “Career Success” and “Social Support”, thus this research, through valid questionnaire surveying 101 insurance agents and 102 real estate agents who age 30~45, shows a detailed analysis on the connection among the 3 factors. From the result of this research, it's found that (1) a positive correlation exists between grit and the career success of a sales representative (2) a positive correlation also exists between social support and the career success of a sales representative. (3) social support has a certain level of interference on grit and the career success of sales representative.
