Know or listen to those who know.
Expect problems and eat them for breakfast.
Leap, and the net will appear.
If you think you can do it, you can.
Either you run the day or the day runs you.
Only the educated are free.
Things do not happen. Things are made to happen.
Who seeks shall find.
If you can dream it, you can do it.
You never know what motivates you.
Science fiction is an amazing literature: plot elements that you would think would be completely worn out by now keep changing into surprising new forms.
