I can, therefore I am.
Well done is better than well said.
Be thine own palace, or the world's thy jail.
Be gentle to all and stern with yourself.
Never complain and never explain.
Wherever you are - be all there.
Do not weep do not wax indignant. Understand.
Know or listen to those who know.
The secret of getting ahead is getting started.
By failing to prepare, you are preparing to fail.
Science fiction is no more written for scientists that ghost stories are written for ghosts.
