And then on the flipside there is Musk, Jobs, Gates and countless others who work(ed) all the time. All I'm saying is I see a lot of emulation-of-success articles posted here...
Those people are not scientists. Lookup Musk on Wikipedia and you'll find that he has a BSc. only, and he started a PhD only to quit after a few weeks to pursue his business endeavors. Jobs dropped out of University. And Gates is probably closest to a scientist, although I'm not aware of any research by him.
Having PhD or working on it is not a prerequisite for being a scientist. Musk is not in academics, but he is a CTO of a SpaceX, so he is in charge of scientific and technological issues within an aerospace company. He does more applied science than vast majority of scientists that I can think of.
