Stop being too obsessed with productivity.
The productivity of a worker is rather important.
The amount of work you do says something about your ability, but only in a limited way.
Besides, comparing two people’s ability simply by the amount of work they do is really not a smart way.
Such value is used to judge the assembly line workers in the industrial age, and it is obviously inappropriate to judge today's brain workers.
If you think about how to do more work every day, your mindset will become increasingly fixed, and your ability to solve open problems will get worse over time.
Moreover, this way of working will take up your time when you should be making strategic planning. Instead, you are only trying to become a better-functioning part of a machine, which is definitely not good for your long-term career development.
