I often experience what I call "perfectionism block".

It's a different kind of block than art block.
When you have art block you want to make something but you can't find an idea.
You may end up staring at a blank piece of paper all day and you still don't know what to create. It's frustrating.

What I mean with "perfectionism block" is perfectionism that makes it difficult for you to make and finish art. It's when you have an idea, start to create something,
but get stuck in the process or end up proceeding at a very slow pace,
because you can't say when you're over with your creation.
You might feel like you want to add more, or you might end up adjusting elements over and over again because they don't feel right.

I might have a great idea that I want to put into practice, but I know that I'm unable to do it,
or at least that it will never be exactly as I imagine it, so I start and it takes... forever.
No matter how many adjustments I make, it never fully satisfies me and sometimes I end up abandoning my work.
There's always something that looks off.

I get mixed thoughts like "What if I added more? It looks kind of incomplete and too basic"
and "Maybe it's already good enough like this, there's no need to make it too complex or it might get messy".

At times I focus way too much even on things that are supposed to be more rough, like sketches.
So I get stuck at the beginning. I try to remind myself that it's fine if something doesn't look "perfect" at the beginning
because I'll end up modifying it in the process and everything will slowly take its shape.
