It is possible to commit no mistakes and still lose. It’s not a failure, it’s life.
“He makes his sun rise on the evil and on the good, and sends rain on the just and on the unjust.” -Matthew 5:45
A business professor told me the reason he was successful was because he always got back up. When he failed and it was his fault, he learned a lesson. When he failed and had done everything right, he learned resiliency. He became a stronger, tougher person.
Sometimes the most bitter losses result in the most growth. Sir Edmund Hillary was the first person to conquer Mount Everest, along with Sherpa Tenzing Norgay, but he didn’t beat it on his first try. His first attempt was a failure, even though he did everything as correctly as was possible. After that, he looked at Everest and said,
“I will come again and conquer you, because as a mountain you can’t grow, but as a human, I can.”
When a loss takes you by surprise, use the opportunity to become more resilient. Get back up and grow.
