Developing an aesthetic is like handwriting. You keep doing the work, and it will naturally be displayed. Through praxis you encounter and overcome your flaws. In the struggle to create everything you love, you will encounter everything you hate. These dragons must be destroyed, one by one. And through those battles you will develop scars. An aesthetic isn't just the display of skill and medal of work, but also the bearing of flaws and the demonstration of failure. Because we are not the artist, those weaknesses aren't detected, and the mistakes remain hidden. But from the artist's perspective, all his works are bankrupt of the divine inspiration he tried to produce. Thus, no artwork is complete; merely abandoned.
To define aesthetic from the point of view of the observer and collector; they seek cohesion and consistency. This is the comfort that appeals to the market. But the artist that is true to himself is capable of constant invention and embraces the eternal struggle with himself. This is upsetting to those who want to return to the same flavor over and over again, that is to say, to buy and collect the art. They wish to capture the artist in the art, and thus many artists are caught up creating a brand, instead of searching for the beauty through the eternal destruction of who they were, in order to become who they are.
