Is there a proverb that advises not to panic in bad times and not be overjoyed in the good times? I mean to be patient in both the good and the bad times.
Or, in other words
● Don't be overly delighted in happiness and don't panic in sorrow. Keep balance/be patient in both.
● Life has its ups and down, don't be overjoyed in good times and don't panic in bad times.
Is there a commonly used 'Proverb/phrase' in English that says it ?
