Looking at how society as a whole generally/broadly defines "success", yes, there are a few cases were not making millions or more is still considered [extremely] successful, but more often than not, "success" at the level of people like the founders of Instagram usually means making bank.

I am in no way agreeing or disagreeing with this notion of "success", just stating how I think society in general broadly feels.

Heck the OP has such a vague definition of success (it changes from lines 1 to lines 3) that its basically discussion bait/fluff.

Line 1 basically refers to stuff like learning code, while line 2 seems to allude to success in terms of making bank.

depends on your definition of success
