In Japan, a well known proverb is: Saru mo ki kara ochiru (猿も木から落ちる).
This translates as: Even monkeys fall from trees.
And its powerful meaning: Even those who are masters in their own field of expertise make mistakes.
Remember, that no-one is perfect no matter how much they practice.
Even the monkeys who spend most of their lives climbing trees, sometimes fall.
It’s OK, just climb back up again and continue as you were.
