When I was a student, and college became more and more expensive, I too had to get a job. I too had to work between midnight and four o’clock in the morning because we got 25 cents extra an hour by working the graveyard shift. So I worked for the physics department for two years and was able to finish my undergraduate work. And instead of complaining about that — instead of complaining about the fact that my roommates were all going out on Saturday night, they had say, a second-hand car, or they all went home for vacation when I stayed to make extra money so I could make it through the next semester — I faced it and embraced it as part of the learning experience. The learning experience of life. She imparted the strength which has carried me right through. That has helped me at every step in my career.
