What distinguishes the true artist from not present?

[Veronic]

on the topic .... I think that let the artist decides to present it or not, and in consequence it is only for the him and it is important.
Now my vision

If a person is engaged in something else, not creativity, then there was an artist and because of lack of money stopped painting while suffering terribly, then he is a true artist.

If draws and dreams that had a lot of money, and I agree for the money to leave the case, that means not real.

If the draw, but can not sell ... it does not throw, and does not think about quitting, then this.

If paints are sold well and happy, then this ...

If paints and sells well and dissatisfied, while not real, because it would have chosen for themselves any of the previous versions.
