The way that we are given a choice every single morning when we wake up how we will approach that day. We can peep out from under the covers fearfully, or we can leap out of bed and attack the world as if it were a pile of Christmas presents under the tree.
Owning my own life, now that I'm an adult. I didn't have good parents, and I needed a lot of medical intervention, so simply being alive and having dominion over my own life is my greatest joy. Sub-joys are that I have a house, and a garden, and cats, and a decent spouse, and a job I love, and a car that runs, and hundreds of books, and a 1960 restaurant stove with two ovens up top and burners on a drawer that pulls out -- all working well, which is important because I like to cook. Sounds like a dull life, but it's my life and my parents are both finally dead.
