Failure is often filled with embarassment, shame, and sometimes guilt. Because of the shame mostly, we are motivated to avoid failure and sometimes to lie about it to save face. Of course this a perverse and pernicious priniciple because we learn from mistakes and failures all the time. Watch a baby learn to walk, How many times does the baby stumble and fall? Watch a person learn any skill like riding a bike. How many times must they fall before they learn to keep their balance?
Mistakes are a staple of life. Cursed is the person paralyzed because they are inert out of fear of making a mistake.
Creativity and success requires risk and the willingness to make mistakes, to fail.
I tell people to make as many mistakes as they like. My only rule is that when you make a mistake take respoonsibility for it and clean up your mess. Don't put it off on others by blaming them or leaving the consequences for them to repair.
