This is excellent advice for any single person, or person in a committed relationship who is not happy and seeking to forge their own way.

The only "but" is you're leaving out one key component, of a partnership: trust.

Trust includes finances.

In most couples that I have been part of, or known closely, one person is better with money than the other. The one who is better with money, should generally manage it. Of course, details are for the partners to work out. But if there are power/control games, or mistrust of any kind, then it's not a partnership.

But, as somebody who has been an artist myself, then later when I got financially responsible was with an artist later... living a left left-brained life such as reconciling a budget, managing one's own credit, and following through with formal education just aren't interesting to everybody.
