Hey there!
Perfectionists are always afraid of what others will think about them. They fear that everything they do might not be "perfect" enough for others and that they will be criticized for their mistakes. Perfectionism can cause anxiety. When perfectionism is reduced, people aren't afraid to make mistakes and try new things.
Hope it helps, and sorry, I have to go now. I have an essay on culture, and a presentation, and another one about the Emancipation Proclamation, and another one about the impact of humans...
Goodbye!
Have a great day!
