To know oneself, one should assert oneself.
Quality is not an act, it is a habit.
Always desire to learn something useful.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Do not weep do not wax indignant. Understand.
You never know what motivates you.
The dog that trots about finds a bone.
Be kind whenever possible. It is always possible.
Things do not happen. Things are made to happen.
Dispassionate objectivity is itself a passion, for the real and for the truth.
If you only have a hammer, you tend to see every problem as a nail.
The story of the human race is the story of men and women selling themselves short.
