It’s worth mentioning here - the founder (Dhiru bhai) of Reliance used to pump gas in Dubai and that’s where he got the dream to start his own refinery one day. Dream one side, but just going about setting up such a giant production facility at an enormous scale is nothing short of an extraordinary achievement. Pretty sure he had overflow of grit, commitment, and all around strength, and of course high dose of highest level of talent.

Nah, he did it the old-fashioned way - by corruption and dirty dealing, then his family suppressed the people reporting the truth:

They're still playing above the law and read anti-corruption regulations as "how to" manuals.

Any source for this claim that Ambani started his career as a gas pumper? Or are do you mean someone else?
