Quality is not an act, it is a habit.

What you do today can improve all your tomorrows.

Well done is better than well said.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

You never know what motivates you.

Begin to be now what you will be hereafter.

Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.
