In order:
Women.
Martial arts, combat and warfare.
Physics.
Saving our species from ourselves and whatever else might threaten our existence.
Everything that has anything to do with MARY JANE, my lovely wife.
Knowing, experiencing, and witnessing everything the universe has to offer.

I can think of nothing else, but there is much more. Im kind of sad to see Mary Jane so far down on the list, but that is the nature of things.
