The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
You never know what motivates you.
Be thine own palace, or the world's thy jail.
The dog that trots about finds a bone.
I can, therefore I am.
Always desire to learn something useful.
After a storm comes a calm.
If you can dream it, you can do it.
If you've got a talent, protect it.
The scientist is motivated primarily by curiosity and a desire for truth.
Science, almost from its beginnings, has been truly international in character. National prejudices disappear completely in the scientist's search for truth.
