If you are lucky, you stop seeing the world as a series of things you do not have — a boyfriend, a baby, an adorable terrier – and you start noticing the things you do have. A healthy bank account, unburdened by mortgages or school loans. No romantic ties. Loving parents who wanted nothing but happiness for you. Years to burn. That kind of freedom is like a command from the universe to get off your ass and do something amazing.
