I used to take a lot of pride in my work when I was younger. I prided myself on producing the best quality work I could and rarely gave in to laziness or cut-corners at the expense of quality. I was unabashedly proud of it. Unfortunately for a long time, I equated pride in my work with pride in the product of my work.
When you take pride in your work, you do your best. When you take pride in the product of your work, you reject all criticism. Constructive criticism is how you improve and rejecting that means stagnation. It took some time for me to learn this but once I did, I noticed how little pride in anything mattered.
Now I rarely care about anything I've made, written, or designed. I don't care if it is endearing or embarrassing. I care that I did it, for the reasons I did it, and with the effort that I did it with. But I don't care that *I* did it. This mindset has led to continuous improvement in everything I do. So criticize away. If I have the time and resources, I will incorporate your suggestions with an open mind.
