To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Either you run the day or the day runs you.
Quality is not an act, it is a habit.
To be a good loser is to learn how to win.
Problems are not stop signs, they are guidelines.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
The secret of getting ahead is getting started.
If you've got a talent, protect it.
If a weakly mortal is to do anything in the world besides eat the bread thereof, there must be a determined subordination of the whole nature to the one aim no trifling with time, which is passing, with strength which is only too limited.
