Be thou incapable of change in that which is right, and men will rely upon thee. Establish unto thyself principles of action; and see that thou ever act according to them. First know that thy principles are just, and then be thou.
Good character is more to be praised than outstanding talent. Most talents are, to some extent, a gift. Good character, by contrast, is not given to us. We have to build it piece by piece -- by thought, choice, courage and determination.
A good character is the best tombstone. Those who loved you, and were helped by you, will remember you when forget-me-nots are withered. Carve your name on hearts, and not on marble.
Character is the foundation stone upon which one must build to win respect. Just as no worthy building can be erected on a weak foundation, so no lasting reputation worthy of respect can be built on a weak character.
Character isn't something you were born with and can't change, like your fingerprints. It's something you weren't born with and must take responsibility for forming.
