I think the answer to this is obvious: Health, of course! If you are healthy you can work to become wealthy, if this is your wish. If you are really unhealthy but you have plenty of money you might well be able to afford the best medicos. But if they are able to cure you to the point where you are no longer deemed by them (and yourself more importantly) to be healthy, you are no longer unhealthy and therefore out of that category.
But the chances of becoming wealthy and, at the same time, leading an enjoyable life, are far greater than if you are wealthy and endeavouring to get well. I'd rather be slaving for a wage in a factory than sitting in a wheelchair all day.
Of course, the best is to be both healthy, wealthy and WISE. The last is very important. If you are wise then the chances are you will remain both wealthy and healthy. If you're not, "A fool and his money are soon parted," as they say. And if you're not reasonably wise, then you'll let your health deteriorate. So...without a reasonable modicum of wisdom, you could well end up both broke and unhealthy.
