Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

Either you run the day or the day runs you.

Things do not happen. Things are made to happen.

The wise does at once what the fool does at last.

To know oneself, one should assert oneself.

Never complain and never explain.

If you think you can do it, you can.

The dog that trots about finds a bone.
