Well to be honest I pondered about this topic for a while and here are my conclusions:

Types of passion:

1. Goal, passion to complete
2. Peer, passion to compete
3. Life, passion to survive

Now the original article says

1. passion for nothing
2. passion for one thing
3. passion for everything

People with a passion for everything are not interested in things themselves, they’re interested in interest.

The 3rd category is particles in the beginning of an explosion, 2nd is the flying out splashes, 1st is the long dead ones. It's funny because my observations is based on statical, scalar behavior of passion, while the author is more time-oriented and a vector field, which is what the true passion is about.

Mine is too informal :(
