It is just so difficult to get them done right. It's almost impossible. How many people are getting quality sleep? I'm afraid that's a very expensive commodity and even rich people might not do that right.

Just a note that my completion rate and tolerance to grit increase dramatically when I had a good sleep, which is very very rare nowadays.

Rich people have more pills, from what I've seen. I agree that it's very difficult. But it's also very valuable.
