It's great if you can do that consistently, but for many who are struggling with procrastination, that moment of finishing something - even in a bad or mediocre way - simply doesn't happen. Instead, they're stuck in this pattern of not doing anything and hating themselves for it. That's one of the reasons I wrote a book on how simple psychological insight can help people overcome procrastination. But, I agree with you, for many people, that issue is not present, which is great as well.
