It's hard to not take things personally
It was hard not to take Prototype’s failure personally. Critical blog posts felt like a full assault on my values. And seeing friends use other libraries made me feel like my work was a waste.
It's part of the pain of being a creator, to watch the world interact with your creation, without regard to your feelings or the process you had to go through to get to the place where you were able to create it.
But in response to Sam's post: Learning to not take anything personally is a great life skill for all of us to master. Whether it's the rude guy in line at the supermarket or your wife or boss being upset with you. It's never about you.
