The wise does at once what the fool does at last.
The dog that trots about finds a bone.
I can, therefore I am.
Either you run the day or the day runs you.
The most effective way to do it, is to do it.
Always desire to learn something useful.
Without hard work, nothing grows but weeds.
Be kind whenever possible. It is always possible.
Never complain and never explain.
Who seeks shall find.
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.
