To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

The most effective way to do it, is to do it.

The wise does at once what the fool does at last.

What you do today can improve all your tomorrows.

Well done is better than well said.

Quality is not an act, it is a habit.

Be kind whenever possible. It is always possible.

Problems are not stop signs, they are guidelines.
