I do not take criticism of my work personally. I think this is because I have already heavily criticized it myself. Everything I make falls short of the ideal form I have pictured in my head. This applies to code, woodworking projects, CAD models, documents I've written and food I've prepared. These works all feel separate from myself despite coming from my brain. That is not to say I'm not proud of them or feel like I've done a good job; quite the opposite! But at the same time it is very rare for me to feel like there is not room for improvement or even obvious shortfalls.
I think with this mindset it is easy to accept others criticism because I already agree anything I made is needs criticism and is worthy of being criticized. It is also one of the only ways to improve. I get excited when I can get someone to provide feedback on food I've prepared (people are hesitant to do that as it seems rude) because it teaches me what they like. For software, sometimes the criticism is just someone else's preferred style and that I take even less personally and try to work with them to see if there is a middle ground that suits both of us or our team.
