Begin to be now what you will be hereafter.
Problems are not stop signs, they are guidelines.
Be gentle to all and stern with yourself.
Be kind whenever possible. It is always possible.
After a storm comes a calm.
Either you run the day or the day runs you.
Never complain and never explain.
Quality is not an act, it is a habit.
Wherever you are - be all there.
Well done is better than well said.
