Buying art is a lot about connection to the artist—when somebody comes over and asks about your painting choices, you want to be able to tell the artists story.
People connect because of shared experiences and stories. Thus, a part of what an artist sells is their own story.
This applies to any creative person, and is a big part of the reason why indiehackers are so interesting to follow. (which of course makes them more likely to succeed because they Build a diverse network, Talk to people, Work in public etc)
Thus, an important things you can do to further your creative careers is to tell your story.
