Would you be able to share an example of what were those industries/businesses, perhaps ideas that you already pursued and moved on from?

I too feel the people who attribute such successes to luck are missing something.

I’ve had people tell me that a lot of the things I achieved professionally in life (being able to successfully immigrate to the US from another country, get tech jobs in Silicon Valley including Google, get out-of-band compensation, work as an early employee at a unicorn, etc) were due to pure luck, but I don’t believe it. I see so many people around me who followed the same path, and it was perhaps 80% determination and 20% luck.
