Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Who seeks shall find.
Leap, and the net will appear.
If you've got a talent, protect it.
Be thine own palace, or the world's thy jail.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
A sense of duty is useful in work but offensive in personal relations. People wish to be liked, not to be endured with patient resignation.
