This quote means that if we make mistakes and learn from them, we can still be successful. Too often, people give up after failing at something. However, failure can also be an opportunity for growth and success, if we take things away from the experience that we can learn from and apply in the future. Making mistakes is a natural part of the learning process. Rather than looking at failure as a negative, we can look back and see the positive aspects of it – all the things we learned and the new paths it opened up for us.
