Quotations and Literature Forum

Does anyone know who said "The older I get the less I listen to what people say, and the more I watch what they do" or something like this?

I found the line on the Internet, but not as a "quotation"

The older I, get the less I listen to what people say and the more I pay attention to what people actually do...

One learns in life to keep silent and draw one's own conclusions.


Cornelia Otis Skinner (1901-1997)

As I grow older and older
And totter towards the tomb
I find that I care less and less
Who goes to bed with whom.
--Dorothy L. Sayers
