Look for work in areas where you have built-in confidence based on your own experience or preferences. It’s not to say you can’t succeed in areas in which you never thought you had talent, but your shortest path will come through your strengths.
If you like your work, your chances of success will be higher. In the workplace, make your first priority improving your organization, department, or work unit rather than worrying about how the company will help further your own ambitions. Take pride in making everyone better wherever you are. Success takes care of those who create success for others.
