Consider the following conversation.
Boss says to his designer: "We need to modify our design."
Designer: "Why? The client just confirmed it yesterday."
Boss: "They changed their mind this morning. The only constant in life is change"
I know this was said by Heraclitus, an ancient Greek philosopher who lived around 500 BC.
I also know its meaning. I’d like just to know whether this version is widely recognized?
Another version is "The only thing that is constant is change."
Which wording is more common?
Ngram Viewer limits at most 5 words, so, the most common use "the only constant in life" could be
"change is the only constant in life"
"the only constant in life is change"
"The only constant in life is that things change"
I also tried other combinations and didn't get a clear result. Can someone help me on this?
