Spiritual Journey - I'm happy!  Why fix it?

Why should anyone want to go on a safari? Why would anyone want to dive to the bottom of the ocean? Why would anyone want to trek across the Himalayas? Why would anyone want to race a Ferrari? Why would anyone want to jump the Nevis Bungy in New Zealand? Why would anyone want to meet a stranger? Why would anyone want to study medicine, computers, fly a jet, explore space, travel the world, run a marathon, fall in love with a total stranger, move to foreign country or the scariest thing in the world for most of us, why would anyone want to explore our inner self?
