As long as we keep trying, we will continue to make mistakes, thank goodness.
We learn from mistakes made, we might not have made the mistake, but there was someone before us who dared to fail and then shared with others of not what to do. Failure is necessary, it helps us grow.
But failure is not definitive, it is not the end of a process but the beginning of identifying what should not be done. We have to continue the process, keep trying.
Embrace the challenge, accept failure but keep moving forward.
