Animals, tender moments, hiking through a forest after it rains, swimming, strong winds, the smile of whoever I happen to be attached to at the time, grilled lemon pepper trout on top of japanese short-grain rice with a side of miso soup and green tea, being alone in a sunlit room around 12-2PM, with just birdsong, the wind in the trees, and the occasional thrum of a passing car, a good book, a comically bad movie, a bittersweet song, things by Voltaire though that's less a smile and more a devious smirk.
I think that's got it.
