The wise does at once what the fool does at last.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Know or listen to those who know.
After a storm comes a calm.
Quality is not an act, it is a habit.
It's always too early to quit.
Be kind whenever possible. It is always possible.
Expect problems and eat them for breakfast.
Be thine own palace, or the world's thy jail.
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.
