So the next part of the book I've been reading... is all about money matters.

The author begins by talking about perceptions people have about money... the whole school of thought on the "starving artist"... and such. About how artists (in general) tend to think in terms of:
"I am no good with money"... "I don't have any money" .... "selling art doesn't make any money"...
And how improving things to do with money, involve changing our mindset from thinking badly about money... to being a bit more open minded. And believing that, like anything else... money is just a form of exchange. That we are more adept at handling money than we probably give ourselves credit for.
After all, we've gotten to this point in our lives having dealt with money all our life in some form or another. We have experience. We know the value of things, we appreciate the time and effort it takes to make things... we've bought, we've sold.
So then the author talks about changing our perceptions again.
From thinking... I can't afford such and such to improve my art business...
to thinking... how can I make this possible. What can I do to make this thing happen?
So I can work better, advertise to more people, have supplies to make this thing... whatever the case may be.
And how this all revolves around making and keeping a budget.

I know. Believe me. I know.

So the author goes on to describe a simple way to figure out a budget for a project, based on:

~Figuring basic costs of materials
~Associated services: such as if you need to hire an electrician, lawyer, whatever to further the project along
~Adding in missing income. Ie: while you are working on this project, what will you lose in terms of potential sales, time in the studio, etc
The important thing here... is to have a clear number to work with.

Once you know what you need to come up with; there are hundreds of ways to come up with the money... and your mind will automatically start brainstorming ways to do that.
