Be thine own palace, or the world's thy jail.
Know or listen to those who know.
Well done is better than well said.
Problems are not stop signs, they are guidelines.
After a storm comes a calm.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Begin to be now what you will be hereafter.
Who seeks shall find.
If you're going through hell, keep going.
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.
