Ask HN: How would you define a good work ethic?

I started paying attention to my productivity 10 years ago. It waxes and wanes. Right now I'm in a downturn. After an easy day of work, I just browse reddit and YC. It's depressing.

I remarked to my date last night how I wish I was type A. I've seen them at work. They're machines. They literally get done 4x as much as normal people.

However, I remember reading an interview of an Asian billionaire (might have been Li-Kashing) and "capacity to work hard" is what counts.
