Brendon Hartley's unexpected arrival on the Formula 1 scene with Toro Rosso was one of the great stories of the 2017 season, and his experience provides a lesson to people in all walks of life about not giving up on your dreams.
Just a few months earlier the New Zealander's future was uncertain after Porsche announced its intention to quit the World Endurance Championship. And yet at the age of 28 he's heading into the 2018 season with a full-time F1 drive at Toro Rosso, eight years after being dropped from Red Bull's junior programme.
No-one could have predicted how things would turn out for him - a classic example of being in the right place, at the right time. His 2017 season ended with a hectic schedule that meant he was criss-crossing the globe, jumping from the Porsche to the Toro Rosso and back again. He barely had time to catch his breath.
