"I am sure of nothing so little as my own intentions."
Lord Byron (1788-1824) British poet
As with offering to pay for groceries using money you intended but did not bring to the store, your intentions to do most anything are only valuable when you actually do them.
"In all affairs it's a healthy thing now and then to hang a question mark on the things you have long taken for granted."
Bertrand Russell (1872-1970) British logician/philosopher
Whether about religion, politics, or any other silly discussion you might enter into, remember that extremists are those who will not do as Mr. Russell suggests.
