Quality is not an act, it is a habit.
If you're going through hell, keep going.
Never complain and never explain.
Be gentle to all and stern with yourself.
Who seeks shall find.
If you think you can do it, you can.
To know oneself, one should assert oneself.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
If you've got a talent, protect it.
The doubt of an earnest, thoughtful, patient and laborious mind is worthy of respect. In such doubt may be found indeed more faith than in half the creeds.
