At some point in our lives we will all experience failure. It doesn't matter if you are young and inexperienced or an adult with proven skills... It just seems to be the nature of life that things will go wrong. We've all been told to keep trying and not to give up and to some degree that's true. (bigger versions)
The important thing to me is why... I don't think that final success in any given endeavor is all that critical, but rather that the journey to improve doesn't stop. It seems to me that more and more people are overly concerned with the end results and not the process of getting better by gaining skill and experience. People shun their own mistakes and mock those of others. People prance about and define themselves by their past achievements and possessions and not the path they took to achieve them.
While there is nothing wrong with achievements or possessions, something is wrong when society values them more than skill and wisdom. Unlike society, Nature always selects for what really works and not what's culturally in vogue at a given point in time. Eagles miss catches, drop fish, and have them stolen in flight all the time but I have yet to see an eagle pile up more fish than it can eat to show off or refuse to try again after it loses a fish.
For me, the most valuable thing people have to offer to society is the potential for future accomplishments, not what they have done in the past or the objects they own... Failure isn't something to be afraid or ashamed of and prior success isn't something to be proud of...
