How did you reach your first crore?

So I am in my early 30s, and have an almost 1.4lakh take home salary. No matter how much I see up the ladder, I am not able to fathom how is anyone becoming a crorepati in India until you are in c-suite category. The only thing I can see is earn in dollars save in rupees I am auditor in big4 offshore division. Nobody in my family is a crorpati, but i want to be one Hence the question.
