A peril and a gloomy yet salvageable paradox

Passion. It's not enough to just have passion. The passion has to be about something.
Just being passionate is a blissful and fitful state. As a ship without a sail or a rudder, this person will set sail. They will find something and be "useful". Yet there's a certain level of vacuousness in this person. Being passionate about something is a more complete way. Risky but much less vacuous and much more fulfilling in a true way.
