True. Passion is that driving force whose absence would mean the lack of any possibility of success.
We all posses it, in one way or another, some just need to dig a little deeper to discover, or rediscover it.
Be passionate, dare, believe and keep on going, no matter what your destination is, if you are willing to tread your path with determination, it will be worth your while.
