Leap, and the net will appear.
Expect problems and eat them for breakfast.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
To be a good loser is to learn how to win.
I can, therefore I am.
Never complain and never explain.
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.
