You never know what motivates you.
To know oneself, one should assert oneself.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
The dog that trots about finds a bone.
What you do today can improve all your tomorrows.
Leap, and the net will appear.
By failing to prepare, you are preparing to fail.
Always desire to learn something useful.
Only the educated are free.
The art of medicine was to be properly learned only from its practice and its exercise.
