A friend once explained his philosophy to me, that I find helpful: "Once you've written it, it's just code. Someone can always find a better way or improvements and that's fine"

I think the second sentence is true for everyone's code and that's what makes the job interesting.

Also jobs rarely aim for perfection, they aim to create value efficiently for the business. If the best way of getting there is producing code with a few mistakes that are when later picked up in a code review then that's fine too.

If this resonates with you at all, then when something annoys you repeating to yourself "It's just code" might help. Best of luck!
