Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
I can, therefore I am.
Problems are not stop signs, they are guidelines.
To know oneself, one should assert oneself.
The secret of getting ahead is getting started.
Well done is better than well said.
Be kind whenever possible. It is always possible.
Never complain and never explain.
By failing to prepare, you are preparing to fail.
Knowledge once gained casts a light beyond its own immediate boundaries.
