Things do not happen. Things are made to happen.

If you're going through hell, keep going.

The dog that trots about finds a bone.

Problems are not stop signs, they are guidelines.

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.

Quality is not an act, it is a habit.
