An ounce of prevention is worth a pound of cure.
He that won't be counseled can't be helped.
How few there are who have courage enough to own their faults, or resolution enough to mend them.
I wish to live without committing any fault at any time.
Little leaks sink the ship.
You don't get somebody to like you by doing them a favor. That only tends to build resentment over the fact that they are needy and you are not. No, you ask them to do you a favor.
