i think that it's pretty clear that getting rich is largely luck. you were in the right place at the right time with the right skills. if it was more than that, then you'd be able to repeat it without advice, right? given that, two approaches make sense to me: 1 - treat it as a lucky break and consider how best to make it last over the long term, as a one-off. but you say you don't want to do this in your question. 2…
24k a month is near 300k a year... doing pretty damn well, if you can keep it up, but like you said, nowhere near very rich. The very rich get richer because, like Mark Cuban says, when they invest in a company, the CEO gives them a call and asks if they have any recommendations.
which suggests another approach is to use the money to find ways to extend how long this can last. for example, by porting to android.
