Criticism about code is either accurate or useless. If it’s useless, no point getting bothered by someone’s bad opinions. If it’s accurate, then thank god you won’t have to discover it later when it bites you in production. Always good to remember all the times you’ve messed up, makes you appreciate the extra eyes. Plus, no matter the quality, you learn a little more about programming and the people you work with by seeing their thoughts applied to something you made.
