I can get obsessed with anything! I lived near Valley Forge and got obsessed with American Revolution and went there everyday and the museum.
I've been obsessed with music, expensive guitars, audio equipment. Motorcycles a few years ago, hockey autographs several times, etc.
I have no idea why I get carried away with my thoughts. I think I have flight of ideas which is symptom of BP and OCD...
I think something will bring me happiness so I go after whatever it is. But I just end up making myself worse.
