Productivity is something that varies from a person to person. In the tech world, if someone able to master the 'art of managing time' they are the ones whom we should look like Rockstar as they are the most productive.
Every person has at least 2 things - family (personal) and job (remote or non-remote) to manage. Many folks could have - studies (full-time, part-time), some hobby, or some community (like me). The more things(tasks) one has in their life, the more difficult it becomes to manage the time. This brings the struggle to manage everything with quality. As well as, it brings the fall in productivity and increase stress.
