Holiday edition: Essential skills?

My 8-year-old just walked up to me with his clipboard and told me he was going to make a list of all the things I told him he "had to" learn to do before he was an adult. The things I told him when we started talking about it last week were:

  • Ride a bike
  • Play an instrument
  • Swim
  • Roast a chicken
  • Do laundry
  • Apologize correctly

Now that he ante'd up with the clipboard, I'm trying to think of other things I think are essential. But, of course, all our heads together are better than one.

So what are the things you think we should all know how to do by the time we reach adulthood?
