We are living in a new golden age of planetary exploration—there are spacecraft exploring the solar system from one end to the other, and now JPL is engaged in planning the next big mission to the Jupiter system. It won't arrive for many years, and a lot of scientists and engineers will be needed—to work on communications, propulsion, instrument design, project management, spacecraft design, scientists to establish the science goals of the mission, the observations that need to be made to meet those goals, the instruments needed to make the observations, and finally to analyze the data collected. So to get to JPL, work hard in school. Find a subject that you enjoy and stick with it. When you hit a rough patch (yes, I certainly hit a few), remember how much you love this subject and use that to regain your footing. I have always had a great deal of self-motivation, and that was a great help. Once you set your mind to do something, keep at it to achieve your goals. Be disciplined in your approach to work. Don't accept compromises regarding the quality of your work. Strive to be the best in your chosen field.
