I do it for money when I work for someone else or when I provide a service.
The creative work in itself is not a service, I don´t think about a possible customer
when I create something. Sometimes I create something with the intention to
sell a product or do create something which helps me with a service that I´m offering.
p.s.:
That´s also a reason why I think long term collabs don´t work, nobody works
long term on the dream of someone else without a motivation (money).
Exposure and trying out will only motivate people for a very short time.
