I know I'm not a perfect writer. Not even a really good one. So I don't expect too much from my writing quality. It doesn't mean I should give up writing. Quite the contrary. I just need to keep writing more. And not just write, but trying to improve.
Getting started with writing, or anything else your not good at can be taunting. It's not fun doing something you are not good at. But that's okay. Acknowledging that whatever you are going to do won't be perfect. Not on the first try, not on the thousandth one. This realisation can set you free.
You don't have to worry about making it perfect. You can accept your flaws. Just do it, over and over again. And after a while, you might find yourself better at doing it than you expect.
But even then, you shouldn't expect it to be perfect. No matter how many times you have done it. No matter what others say. There is always room to improve.
Perfect is the enemy of good. If you try to do perfect you'll never get it ready. Just accept the imperfection and move on. In the end, it will be perfect in its own way.
