I do not only agree with this note, but also have been in that position in which you would love to continue doing something in the creative field, but either have to move because of the money or because there are other aims to pursue. Otherwise, you would stock yourself in the sameness of the knowledge.
I also believe that in the creative field, when someone feels with some kind of freedom, it forces to develop discipline in each person, a skill that (as I understand) is the base of many artists and the reflection of the real will to do something.
I hope that someday, the field of the arts and culture can be regarded as an ‘ideal’ place to be, and not only as the ‘you-have-to-struggle-in-it’ kind of place, exactly because arts and culture are one of the most important fuels for our social life, so we should be involved with the field as much as we can. In my point of view, Arts and Culture reflect more than what men have created, and are so essential, that can be involved in any subject, quality that I highly appreciate.
