Be kind whenever possible. It is always possible.
Without hard work, nothing grows but weeds.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
Who seeks shall find.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
If we would have new knowledge, we must get a whole world of new questions.
