Marie Curie on motivation and goals

I was taught that the way of progress is neither swift nor easy.

One never notices what has been done; one can only see what remains to be done.

A journey of a thousand miles begins with a single step.

Do, or do not. There is no ‘try.’

Never give in⁠—never, never, never, never, in nothing great or small, large or petty, never give in except to convictions of honour and good sense. Never yield to force; never yield to the apparently overwhelming might of the enemy.
