Switching from indifference towards my own mortality to embracing it to fearing it to believing I'm immortal (because I haven't died yet) to McDonald's to wasting what limited time I have in this life and back to indifference again.
In all seriousness, though, I'd love to leave something behind, something that can outlive me. An idea, a book, an invention, a song, a photograph, memories in the hearts of my loved ones - anything. When I die and I see my life flash before my eyes - even without the flashing, even if I just realise that this is it and close my eyes -, I don't want to feel shame. I want some kind of pride. I want to be able to look back at my life and tell myself that it wasn't a complete waste. That's all I want.
