Ask HN: I made $24k over the last month. Now what?

But I'm facing another problem. I don't know what to do with the money, how to use this very large monthly income to actually make myself rich. The app store income is going to end soon enough - the ecosystem is pretty fragile. Now that I have this raw cash, no debts, have a job I enjoy, don't want or need a car, my apartment is perfectly comfortable, what can I do?

I do NOT want to invest in the stock market, or invest in anything long term like bonds or property. I want to somehow use the money to make more money quickly (within a 2 year time span). But I have no idea! What I know how to do best is the app store, but I want other type of things that do not require much time investment, but give as good returns as that.

What do I do with the money? How do I invest it in making more money quickly?

Have you thought about taking some of the income and using it to hire other developers to increase the number of apps that you've got being developed at once? It seems like you know what works and doesn't work on the app store, so it would probably make sense to start trying to make your efforts scale up.
