It's taken me a while to realise that you don't ever "finish" cleaning up. I'm probably going to die while there are unwashed dishes that I need to do. There will be dirty laundry that needs doing. I will also have things that I've Been Meaning to Get Around To.
Not in a dreary way, but just that this is what it's like going through life. It helps put things in perspective when I realise I'm not actually capable of finishing all my todos. It's just a process that you go through while alive.
