Yes, undoubtedly, when an artist shouts about being the best among all artists, it doesn't look great, agreed. And if they further promote themselves in ads with a cry of "come to me, I'll draw everyone better than anyone!" I sense your smiles. But. If an artist knows how to, for example, decorate a living room or office, or how to draw an apple, or choose brushes, and they write a series of posts about it in their group or profile, why not share this useful series with people? They're not directly advertising themselves. They're not promoting their services overtly and with a shout. They're doing it much more delicately and effectively. They simply provide value in their posts and want as many people as possible to read them to genuinely help as many people as possible.
Thanks to these actions, on one hand, information about the artist spreads, and on the other hand, clients find them and place orders. Everyone reads tons of articles and posts on Facebook. Suddenly, they come across an article by an Artist. The reader likes it and subscribes to a series of similar posts. It's all ethical and beautiful, isn't it? Then the reader feels a connection with the Artist, resonates with something (or doesn't, everyone has their preferences), and reaches out to the artist to buy paintings. Here, too, everything is ethical.
How will you know if it worked?
In my opinion, knowing the answer to this question is very important. People come to me with the request "teach me how to draw." But how will you know when you're already capable and have learned?
Another request is "how to sell paintings?" How will you know when you're capable of selling your paintings? The question is not as simple as it seems at first glance. When I was learning, my teachers of drawing and painting often used to say a phrase for some reason: "Well, now you've learned how to do a job that puts bread and butter on the table." We didn't just draw or come up with ideas. We worked. We thought with our hands. This phrase was uttered every time we submitted our work. A special praise sounded like "This is already caviar on bread and butter." It might seem like a triviality… but you never know what might strike a chord with someone.
This was in the early 90s. Back then, there were no Lexuses, laptops, or iPhones. We used ink and a pen to show frost on bare tree branches. The quality of execution (not the idea or the flight of thought) was evaluated separately. Do you catch my drift? Why am I telling you this? I'm showing you an achievement. What I'm capable of. Doing. Such works and selling them. It hit me literally the other day. And how do you personally understand when you've achieved something?
