No, it's not. Passion is the only thing that gives us real purpose. Without purpose, you might as well be dead.
Yes, putting energy and "passion" into your unique abilities may enable you to reach your potential. And perhaps ultimately decide whether this particular mutation was worthwhile, in the long run.
But if you think "purpose" has some mystical meaning, and judge your existence on achieving it... Passion has evolved only as means to an end, and is not worth glorifying. Not any more than you'd glorify "hunger" or "pain" or "pride".
It's an optimization technique in the rat race called "evolution".
