Perseverance

If it falls your lot to be a street sweeper, sweep streets like Michelangelo painted pictures, like Shakespeare wrote poetry, like Beethoven composed music; sweep streets so well that all the host of Heaven and Earth will have to pause and say, 'Here lived a great street sweeper, who swept his job well.'

Never give in, never give in, never, never, never — in nothing, great or small, large or petty — never give in except to convictions of honour and good sense.
