By wealth I mean nice things, which may be more or less material according to taste. Numbers sitting in an account is not wealth, because wealth is stuff you palpably enjoy, or that otherwise does you some good. If you transform the numbers into something that you imagined, and make it real, now you've got wealth (and, even if indirectly, the wealth has a good chance of making you money through some kind of thriving).
