=What may be done at any time will be done at no time.=
"By the street of By-and-by one arrives at the house of Never"
(Spanish).[511]
=Never put off till to-morrow what you can do to-day.=
"One to-day is worth ten to-morrows" (German).[512] "To-day must borrow
nothing of to-morrow" (German).[513] "When God says to-day, the devil
says to-morrow" (German).[514] Talleyrand used to reverse these maxims:
by never doing to-day what he could put off till to-morrow he avoided
committing himself prematurely.
