His first job was at Denny’s. He famously told Stanford GSB students that he’s cleaned more toilets than everyone in that room combined.
He worked at LSI Logic, then AMD, and then founded Nvidia.
So he started average, went all the way to the bottom, then all the way to the top. What a rollercoaster of a career.
And he’s still married to his college sweetheart. A self-made man who’s successful on all fronts.
