Now you need to define what this passion is all about. Is it anything to do with being emotionally aroused and loving and getting the kick out of what you do? Partially yes. But passion is all about pursuing something knowing the valleys and difficulties involved and yet embarking on a task with full gusto and and commitment, with the big picture in mind and being ready and prepared to face all the challenges. Take that big little step further to say that one looks at challenges and adversities as fuel to gain momentum. The greater the challenge the the more powerful the fuel.
Dont pity the ones who smile at the storm, they are not being stoic, sporting a grin and bear demenour. They may be actually taking fueling break.
