Illustrator and designer Milton Glaser on the fear of failure
Glaser says: "Development comes from failure. ...Within our own confident facade, the thing that we most fear in regard to failure is our own self-acknowledgement that we really don't exactly know what we're doing. ...You must embrace failure."
One of the things holding young people back might be the fear of failure—specifically, the self-awareness that they might not be good (yet) at something, and that their peers will see this. I think this is a principal barrier to sustaining creative confidence past the very early years of life when we often don't care so much what others think of us.
