If you're going through hell, keep going.
To be a good loser is to learn how to win.
Either you run the day or the day runs you.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
You never know what motivates you.
Quality is not an act, it is a habit.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
One must never look for happiness: one meets it by the way.
