John F. Kennedy on motivation and goals

Ask not what your country can do for you⁠—ask what you can do for your country.

Leadership and learning are indispensable to each other.

For in the final analysis, our most basic common link, is that we all inhabit this small planet, we all breathe the same air, we all cherish our children’s futures, and we are all mortal.

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.
