Without hard work, nothing grows but weeds.
Well done is better than well said.
Who seeks shall find.
It's always too early to quit.
Always desire to learn something useful.
The secret of getting ahead is getting started.
Know or listen to those who know.
Be gentle to all and stern with yourself.
Go for it now. The future is promised to no one.
To be a good loser is to learn how to win.
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.
