Pursuing perfection is definitely a bad thing. You should know that no one is perfect, and you are asking too much of yourself. Sometimes I can't do it and I'm tired. It is better to make yourself smaller, easier to complete, and constantly build up self-confidence and make yourself stronger.
Pursuing perfection is easy to get caught up in details, and it is impossible to pursue absolute perfection, which will only make you get deeper and deeper, and the more you get stuck, the more uncomfortable you will be. Life can't be too perfect, out of 10 to 8.
