It’s Monday. You are only working five hours today, right? I bring this up because I recently read this piece in Wired on how that is the right amount of hours to work each day, and how people who worked that way were more productive.
Of course there are a few caveats. For one thing, many jobs are not mainly focused on being productive. Anyone who has a job that requires many meetings can tell you that. But if you have a job that is largely focused on producing things, then try and limit yourself to five hours.
