I have read a quotation by Twain–oddly enough, I saw it in Esperanto, not English–that goes something like this:
“Nothing needs correction more than the habits and preferences of other people.”
Is this rendering accurate? And–If I wanted to track the quote down–what is its source?
I’ve had the impulse to use this quote a number of times, either when some tried to correct me or when I read about some activist(s) trying to change the policies of some organization–like the Boy Scouts–in the name of “rights.”
“Nothing needs reforming so much as other people’s habits.” according to http://www.ling.helsinki.fi/~widenius/clemens.html
Oher sites have slightly different versions, but this appears to be the most accurate rendering.
According to my Barlett’s the quote is from Pudd’nhead Wilson and goes “Nothing so needs reforming as other people’s habits”.
Thanx to both 
On a related topic (also from Pudd’nhead Wilson):
"Few things are harder to put up with than the annoyance of a good example."
Or:
"There is no saint like a reformed sinner"

Each chapter of The Tragedy of Pudd’nhead Wilson begins with a quote or two from “Pudd’nhead Wilson’s Calendar.” The quote you mention occurs at the beginning of Chapter 15 (“The Robber Robbed”), and Born2Read’s Bartlett’s is correct about the wording.
