Only the educated are free.
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.
The dog that trots about finds a bone.
Know or listen to those who know.
The wise does at once what the fool does at last.
Things do not happen. Things are made to happen.
Be gentle to all and stern with yourself.
One of the nice things about science fiction is that it lets us carry out thought experiments.
Some ideas you have to chew on, then roll them around a lot, play with them before you can turn them into funky science fiction.
