My mother could have been anything, but never got the chance. Instead, she raised us so that we could become what she never could.
My grandmother had nothing. When she was 13, she had to drop out of school to care for 7 other children. She ate her first egg as an adult. She never travelled more than 50 miles from home her entire life.
My grandfather was the smartest man I ever knew but never went to school a single day in his life. Instead he did mind-numbing factory work and stimulated himself with books, musical instruments, languages, and people whenever he had energy after work. He died prematurely from industrial causes.
I, on the other hand, was born at the perfect time. I got to go to college and now I'm a computer programmer immersed in thousands of opportunities of the biggest technological change in human history. I am limited only by my own imagination in building almost anything I want. And I make more money than any of my ancestors every dreamed possible. I'm probably the first out of 100 generations of my family who actually gets to do what I want and love it.
It that doesn't motivate someone, I don't know what would.
