Never complain and never explain.
The wise does at once what the fool does at last.
The most effective way to do it, is to do it.
Without hard work, nothing grows but weeds.
Be gentle to all and stern with yourself.
Problems are not stop signs, they are guidelines.
What you do today can improve all your tomorrows.
Quality is not an act, it is a habit.
To know oneself, one should assert oneself.
You never know what motivates you.
To design the future effectively, you must first let go of your past.
