The dog that trots about finds a bone.
To be a good loser is to learn how to win.
It's always too early to quit.
Be thine own palace, or the world's thy jail.
Always desire to learn something useful.
Leap, and the net will appear.
Wherever you are - be all there.
Quality is not an act, it is a habit.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Science fiction is an amazing literature: plot elements that you would think would be completely worn out by now keep changing into surprising new forms.
