I’m back to inviting readers to submit quotations whose origins they want me to try to trace, using my book, The Yale Book of Quotations, and my more recent researches.
Enter your name asked:
“I’d like to know the origin of the statement, ‘You are entitled to your own opinions, but not to your own facts.’ I’ve seen a version of it attributed to Daniel Patrick Moynihan, but it would be fun to know if he’s the origin, or if he quoted someone else.”
This is often attributed to Moynihan. However the forthcoming Yale Book of Modern Proverbs has as its earliest citation for this saying the Deming (New Mexico) Headlight, Jan. 6, 1950, which printed “Every man has a right to his own opinion, but no man has a right to be wrong in his facts.” The New Mexico newspaper attributed it to Bernard M. Baruch. Since 1950 was long before Moynihan came into prominence, Baruch seems to have the strongest claim to priority.
Do any readers have any other quotations whose origins they would like me to attempt to trace?

I would love to hear the source of this “Great minds discuss ideas, average minds discuss events, and little minds discuss people.”
I always contributed the following to my father (and even quoted it at his funeral) but I was wondering if it was ever used in publications. “In order to be(come) happy in life you must be able to enjoy the little things”
Fn. Since I’m (and so was my father) Dutch the above is a translation and I’m not sure happy is the right word since (in my opinion) “geluk” covers both happiness and satisfaction, e.g. “blij” could also be used for happy or joyful etc.
“om gelukkig te zijn(/worden) in het leven moet je kunnen genieten van de kleine dingen”
The quote is actually from at least 1946; this site finds a Toledo Blade article from October 9, 1946 as the source:

It didn’t take long for me to find this. Why didn’t you?
