Franklin D. Roosevelt on motivation and goals

The only thing we have to fear is fear itself⁠—nameless, unreasoning, unjustified terror which paralyzes needed efforts to convert retreat into advance.

When you get to the end of your rope, tie a knot and hang on.

The only limit to our realization of tomorrow will be our doubts of today.

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.
