The secret of getting ahead is getting started.
Be kind whenever possible. It is always possible.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
What you do today can improve all your tomorrows.
If you can dream it, you can do it.
Leap, and the net will appear.
Know or listen to those who know.
Expect problems and eat them for breakfast.
Wherever you are - be all there.
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.
