I'm not incredibly convinced that life must have "meaning," per se... but at least for me, the answer's in my signature: find ecstatic, wonderful, amazingly beautiful moments in the things you're passionate about. For me, primarily it's music, for others, it might be art, literature, quantum physics, football, gardening, oceanography... the list is endless.
But the bottom line is this: living without passion is boring! Find your passions and pursue them. :smile:
