Most people are so focused on not failing in their lives that they limit themselves and their abilities, without failure you won't be able to grow as fast nor as much. My opinion: fail early, fail fast, and fail often.
When you look back in history the most successful people have always failed the most. Thomas Edison failed over 6,000 times before perfecting the first electrical lightbulb. Michael Jordan was cut from his high school basketball team and missed over 9,000 shots in his career. Oprah Winphrey was fired from an early anchor spot and deemed “unfit for TV." Lady Gaga was dropped by Island Def Jam Records after only three months.
Failure is a necessary step in the process of becoming successful. You never really hear of Cinderella stories where everything went perfectly and there were no problems while on the journey of success. The only way to figure out your true potential is by walking into the unknown which in turn will eventually result in mistakes and wrong turns.
Failure in the American culture has been labeled as a negative cognition. The idea of failing is not an option in our perfectionism culture where everything has to go as plan and everything must be calculated. The only true way to grow though is by sticking your head out into the unknown and discovering new things about yourself that you had never known.
When you fail it helps to build your character and resilience, it also always give you insights into what you are capable of doing yourself and your work ethic and dedication. Failure helps to grow your personal experience and knowledge base, skills and talents. In retrospect the more you fail, the more you actually know and can offer as consulting measure for others looking to do similar.
In the end you need to look at your failure differently, don't look at them negatively but take the time to reflect on your past experience and use them to make better decisions in the future. Your failure weren't placed in your life to slow you down but to show you how not to do something so the next time you can complete a process faster and more efficiently.
