I don't know whether you have enough money to cover your costs (I assume so, you sound quite successful), but I think it would be interesting to seek out promising founders and take a little bit of equity, instead of another "bunch of money"(tm). That increase in money is not going to significantly change your life, getting an early in at a startup might though. And in addition to that, you'll probably enjoy building that umpteenth MVP a little more if you have the feeling that the quality of your work has a potential stake in your future.
There's of course a lot of my making assumptions here, but I think it's an interesting thought to consider.
