Handling criticism of your song

If a pro-writer's criticism makes you angry, you probably need to rewrite it. Because down deep, you know they are right and there is a problem with the song. Let a little time pass before you dig in and rewrite so you're not "writing angry". Come back later and consider their suggestions seriously. See if you can incorporate their suggestions into your writing while keeping a positive attitude. The goal here is to come up with something you like even better, while also addressing these criticisms. When is it okay to disregard a suggestion from a pro-writer? When you've already thought about what they've suggested and you just made a decision to do exactly what you've done. ie: The girl leaves at the end. (and that's how I want it to stay). Even a pro-writer would tell you to stand up for what you really believe in regarding your song.
