What do you call him? Or her? Or them?
Do you believe in life after death?
Why are you here?
"Finding Your Passion" is a great trend right now and many coaches build their practice on helping clients with this quest.
It may be hard to entertain this notion, but "the pursuit of happiness" might just be a primarily Western, if not uniquely US approach to life. More than that, it's an expectation here, isn't it? Someone asked me today if Germans always strive to be happy, and I guess we do, in a way, but most of all we get on with the business of living. Sometimes, things don't work out, and that's ok, too.
Have you found your passion, your purpose? The thing you can't not do? And does it always (have to) make you happy?
