“A stumble may prevent a fall” speaks to the enduring human spirit of trying and falling and then getting up and trying again. It speaks to the mistake you recently made and how it makes you wiser more stronger for the next time.
My eldest child at university fell behind in his understanding of inorganic Chemistry. He had to work many days of his summer to catch up. This wasn’t fun for him, but he did the work and caught up.
I felt annoyed that he had let the situation progress as it had. I then remembered, “A stumble may prevent a fall.” He learned it is easier to keep up than catch up. He learned if you have time to do it again you have time to do it right the first time. He learned that avoiding a topic you would rather not think about, doesn’t make it go away.
These are important life lessons. Learning this in college before a career was valuable. If you continue to learn from these missteps and ‘fall forwards’ that is all anyone can ask
