The wise does at once what the fool does at last.
If you think you can do it, you can.
The secret of getting ahead is getting started.
Well done is better than well said.
If you can dream it, you can do it.
If you've got a talent, protect it.
Never complain and never explain.
Quality is not an act, it is a habit.
Be thine own palace, or the world's thy jail.
Go for it now. The future is promised to no one.
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.
