It doesn't matter what you picture your job as so long as you picture yourself doing an outstanding job and loving every moment of it. Take 15 minutes daily. Give yourself 15 minutes each day to visualize yourself as a success. Take that time to review those goals. Nothing remains constant and you'll find your goals changing as your needs change, as you become more experienced in understanding the direction in life you're taking, and as you start achieving some of your first goals.
Success does depend on effort, talent, determination and a combination of so much more.
But you are one step ahead of the game when you believe you can reach your goals.
