I still do not figure out a way yet, meaning systematically, how to measure employee happiness is very hard. But one thing we are doing here is, at least we tell employee, right? "When you wake up in the morning, do you feel happy or not? If you feel happy, please come to office. If you do not feel happy, you can stay at home." Right? Figure out the root cause. And it's every day we talk about that a lot. So Freddy, you're right. If you do not smile every day like this, you feel like, "Oh, something wrong," right? I think that the goal is make sure employee happy, but how to measure that is really hard. We do not know.
