I love this one! I ran across these words of wisdom from W.F.Ludwig from a 1923 quote. Not sure where the magazine is quoting him from though.
September 1, 1923 PR E S T O Magazine source - arcade-museum
And by the way, last Monday's "deep stuff" was:
"You will know enough to take advice when you
know enough to know that you don't know much."
It was submitted by Wm. F. Ludwig.
