Remember, art isn't a talent. It's a skill that you can build.
The quality of your art is based on your dedication to it and that alone - nobody is born better than others, but some people may have started earlier, or have more time to dedicate to practicing their hobby. With time, you'll become your best self! At a certain point, you'll look back at your progress and thank yourself for never quitting. And then you'll keep going.
The path to improving art is a linear, positive path - practice more, enjoy more, improve more, and soon slowly you'll develop more and more of an appreciation for it
