The most effective way to do it, is to do it.
Be gentle to all and stern with yourself.
Be thine own palace, or the world's thy jail.
Things do not happen. Things are made to happen.
After a storm comes a calm.
If you've got a talent, protect it.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Never complain and never explain.
Only the educated are free.
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.
