This is an interesting question. But I am glad someone asked it.
Personally I am very happy with my own work and the progress I have made. Ofcourse I want to get better and I look up to a lot of photographers and take their work as an example. There have been times where I did a shoot, came home and opened the images on my pc and I was really disappointed with the results. I still encounter this problem sometimes. My last few shoots I would say I will have 3 good ones and 1 that somehow just don't work. But like I said overall I am very happy with my own progress. Am I anywhere near where I want to be? Heavens no, but as long as I see myself grow as a photographer I am confident that one day I will. :)
I think it's a good thing to always find ways to better yourself. When I notice that my work isn't improving anymore I try to find workshops of photographers I admire to learn something new that might elevate my work to the next level. I have traveled literally to the other side of the world to do a workshop with Peter Coulson for a week. This really helped me a lot on my studio work, but I notice that now I try to find more storytelling in my images. So I will search for a photographer who I think does a great job at that and try to find a workshop to learn this. You need some kind of mentor or teacher to direct you in your photography journey to get where you want to be.
What you could also do is learn from studying the works you absolutely love. I always try to scroll on instagram or whatever and when I stop because a photo draws my attention, I try to dismantle it by looking for the things that made me stop scrolling by seeing that photo. And also try to find out, from what angle was this picture taken, what kind of lighting has been used, from where is the light coming, are there multiple light sources? It's also training your eye and mind to understand photography and light and then apply these things in your next shoot to see if you can replicate it so you know you understand the techniques that were used on the photo that inspired you. Buying photography books of photographers whose work you admire helps a lot with this as well.
That is my approach. I hope it helps you in your photography journey. :)
