Without hard work, nothing grows but weeds.
Be thine own palace, or the world's thy jail.
Never complain and never explain.
Leap, and the net will appear.
If you've got a talent, protect it.
Wherever you are - be all there.
To know oneself, one should assert oneself.
After a storm comes a calm.
If you're going through hell, keep going.
Things do not happen. Things are made to happen.
In hard-core science fiction in which characters are responding to a change in environment, caused by nature or the universe or technology, what readers want to see is how people cope, and so the character are present to cope, or fail to cope.
