I saw this nifty quote today from Napoleon, the great general who happens to be a genetic relative of yours truly and a first class quotesmith. But I have learned one thing in my many years of writing, before you disseminate something like this, you better make sure that your guy or gal actually said it. Too much fake garbage out there in the public ether.
I headed for Brainyquote, my "go to" quote source. Something similar but not exact. So I googled Napoleon, never interfere and came up with this.
