Why do some people have successful career?

I have asked myself why some people have successful career while others not. Like in every aspect of our lives, some are successful and others are not. Success in any career shares the same principles as used in entrepreneurship or in wealth creation. The main principles are strong desire, committment, goal setting, strong education. If one can meet these qualities, he will be successful. On the contrary, the career will be unsuccessful. The notion that the boss will guarantee success to my career is not true. You are the one who guarantees your job and, consequently, your career. Therefore, ask yourself how you should apply these principles so you have a successful career. Think about it!
