I want to try something new: As little work as possible on weekend. First, I want to see whether a break, a real one, can enhance efficiency on weekdays. Maybe fewer A and more B would lead to better results in both A and B. So it is still about work: Trying to treat work and leisure not as two parts competing for the same resource, but as two parts that can benefit each other. Second, I should be fair to my family. Ultimately, I can be replaced at work. Many people are replaceable at work. But my role as a member of my family is unique to me and cannot be replaced.
(... but let's see whether I really can stick to this plan. :p)
