If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
Be thine own palace, or the world's thy jail.
Do not weep do not wax indignant. Understand.
Leap, and the net will appear.
Expect problems and eat them for breakfast.
The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
Without hard work, nothing grows but weeds.
The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.
