Who seeks shall find.
Never complain and never explain.
You never know what motivates you.
The dog that trots about finds a bone.
If you think you can do it, you can.
To be a good loser is to learn how to win.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
After a storm comes a calm.
If you can dream it, you can do it.
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.
