What you do today can improve all your tomorrows.
Expect problems and eat them for breakfast.
Know or listen to those who know.
Problems are not stop signs, they are guidelines.
Begin to be now what you will be hereafter.
Leap, and the net will appear.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
Only the educated are free.
Always desire to learn something useful.
Now it is quite clear to me that there are no solid spheres in the heavens, and those that have been devised by the authors to save the appearances, exist only in the imagination.
