Steve Jobs was famous for starting Apple Computers. In a speech to graduating students at Stanford University, Jobs told students about some of life-changing experiences. Jobs believed these experiences helped him achieve success.

Job's biological mother was a college student. As a young mother, she felt unable to bring Jobs up so she put him up for adoption. Job's adopted parents were simple working-class people. When Jobs was 17, his parents used their saving to send him to college.

After six months of college, Jobs decided it was not for him. Around that time, he had read a quotation that went something like,“If you live each day as if it was your last, someday you’ll most certainly be right.”The quotation made him think about his life and his future.
