Everyone is a millionaire where promises are concerned

A promise must never be broken

When a man repeats a promise again and again, he means to fail you

You can make any promises as long as you are not going to be there to fulfill them.

He who is most slow in making a promise is the most faithful in performance of it.

Stop a bit and think it over. There do be some knots mighty aisy to tie but the untying is a cat of a different brade.
