Answer; 

Passion is the ability to be creative, (to find out or to come up with new ideas, to use your affective ability of thinking, to be interested in, to look for new inspirations, or to be inspired, to be willing to learn), so that the choices, decisions and the responsibilities which pertains to one’s life may be done and expressed in the best way. 
Passion enables us to be able to fulfil our goals in life.

But on the other hand, things which people do with out passion are the responsibilities which one does because he must get them done. Not because he loves what he does, but he does what he does because he must do it.

Forexample; people do jobs, some are in marriages, etc that they are not passionate about. And the things that people do with out passion are some times those things that people do while they are complaining, forcing themselves to do it because somebody else said that they should do it, doing a job just for the sake of making money and not because of the love for the job etc.

Passion is the driving energy which makes us to do our level best, to commit, to make a decision not to fail, to be determined, to be willing to change, to sacrifice, so that we may be able to do the things we love in the best way that we can.

Living life is all about being passionate about life. If you do not have passion about the life you are living, then that means that you need to do some adjustments, so that you may be able to find that passion.
