I was stuck at the texture studies for a couple years because I fixated to the point where I made it more overwhelming than it actually was. I knew from experience that I can occasionally do that to myself and knew I just had to not let myself be intimidated and take things a step at a time.

Ultimately I started paying for official critiques and made myself take it more seriously. I briefly upped my ADHD meds and powered through it.

Of course, ymmv. I could maybe help more if you gave more specifics.

For what it is worth I trust that, if it is something you really want, then you can do it(become good at art). Obviously I don't know you. And it isn't that I believe this is something so easy that just anybody can do. Art is very hard. It is the distillation, a hyperfocusing, of all our basest struggles and doubts. But ultimately it just requires confidence in one's self, constant effort, and desire. The things that stop a person from being good at art are all in that person's decisions. They can be overcome with just a daily choice to dedicate yourself to doing better than the day before. It is both simple and difficult in that way.
