If you can dream it, you can do it.
The most effective way to do it, is to do it.
After a storm comes a calm.
Problems are not stop signs, they are guidelines.
It's always too early to quit.
Either you run the day or the day runs you.
Only the educated are free.
If you've got a talent, protect it.
If you think you can do it, you can.
If you're going through hell, keep going.
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.
