Do you compare yourself to your peers? Or to the established artists you admire?
That strategy guarantees frustration. If you want to advance your own work, yes study other artists from the past and present and learn from them.
But never compare your work to others. You can only measure your own progress from one point. Where you started.

Indie artist Mia Araujo has written an outstanding post on her Patreon page. She describes the impact of looking back.
Here's an example of Mia's recent work
Mia found her project in her own unique take on "Alice in Wonderland"
Here's an excerpt ...
"This was a decade full of failure for me, which was once my worst nightmare. In 2012, I was a terrified-of-the-world late bloomer of a girl, $20k in debt, with a stagnant gallery career. And I was deeply depressed due to this and family turmoil. It was the first time that my art had failed me emotionally and financially, and I had moved out for the first time. I didn’t know what to do.....
I tried making my gallery art work for another year, and tried looking for art-related jobs. Being a traditional artist whose art was not commercial, and whose skills were massively lacking for studio work, this search proved fruitless. In 2014, I swallowed my pride and took a minimum wage job to pay the bills, since it was the only job that would hire me. Making this choice and finding a therapist, helped take the financial pressure off my art so I could get out of my depressive rut. I started working on the seed of an idea that would soon become my Alice project."
