What is success in art? Is it fame? Is it artistic satisfaction? Is it the sense of fulfillment? Is it even correct to consider success in art?

It is clear that if you are defining your marketing success, then it is about money. The business dimension of your art activities can be calculated and measured numerically; your measure of success is based upon the money you made from selling your art. Art business success should be separated and kept apart from artistic success. The topic of this discussion is success in the art market.
There are many aspects to consider before entering the art market, but the fundamental choice you have to make is between making art for money versus making money from art, and / or finding a middle ground between these two.
Are you making art to earn income; or is making art a priority for you by itself, and earning of income from your art only a secondary (although important) goal? Can you fuse these two aspects into a single approach for your art ?
