Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
Who seeks shall find.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
Either you run the day or the day runs you.
Leap, and the net will appear.
Always desire to learn something useful.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
It's amazing that something only an atom thick can be an impenetrable barrier. You can have gas on one side and vacuum or liquid on the other, and with a wall only one atom thick, nothing would go through it.
