"we should not be ashamed of things not going right"
Being a father, I have had the opportunity to watch my child learn to walk (many years ago now).
These days, I often reflect on that. An infant does not start walking from one day to the next. There's a lot of leg exercise to start with. That is followed by standing up, generally next to a low table or chair. It takes a few weeks before the infant is capable taking its first few steps.
That is a lesson we all need to re-learn : it's okay to fail, because you never succeed 100% on the first try. Charlie Brown was right, failure is the best teacher.
Babies know that. Adults need to re-aquaint themselves with the notion.
