What you do today can improve all your tomorrows.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Always desire to learn something useful.
You never know what motivates you.
If you think you can do it, you can.
If you've got a talent, protect it.
The secret of getting ahead is getting started.
I can, therefore I am.
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.
