To know oneself, one should assert oneself.
I can, therefore I am.
Know or listen to those who know.
Well done is better than well said.
Quality is not an act, it is a habit.
The wise does at once what the fool does at last.
If you think you can do it, you can.
If you're going through hell, keep going.
Without hard work, nothing grows but weeds.
Expect problems and eat them for breakfast.
I had no occasion for an apron on that morning.
