The wise does at once what the fool does at last.
The dog that trots about finds a bone.
You never know what motivates you.
Know or listen to those who know.
What you do today can improve all your tomorrows.
Be kind whenever possible. It is always possible.
Never complain and never explain.
Expect problems and eat them for breakfast.
Either you run the day or the day runs you.
Without hard work, nothing grows but weeds.
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.
