As someone in their 50s myself. This is a great list. One thing I would say is that have a plan for retirement early on. Have a hobby, something that will bring you joy when you are no longer working fulltime. I see too many of my friends abruptly retiring after long careers with nothing except a pile of money and are bored out of their minds and depressed. It's a fine balance between working hard and getting ahead but also making time for things outside of work.
