After a storm comes a calm.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
If you're going through hell, keep going.
Well done is better than well said.
Begin to be now what you will be hereafter.
Never complain and never explain.
Quality is not an act, it is a habit.
The world is my country, science is my religion.
