who wins???? destiny or mind!!!!

Its often said that you should work hard because only hard work can pave your way to success... and then as an individual you start with your hard work because you need to prove a point to the world... you need to fulfill your aspirations. But then at a point destiny takes a turn and makes you reach a place that you hadnt imagined.... you feel that i work so hard and then one strike of fate and my world is topsy-turvy.... then who wins???? destiny or mind!!!!
