This kind of thing is a joke. If you take the time to try to schedule your entire year like this, you've gotten into the wrong career. Sure, you have to work tons of hours, but if you are trying to calculate from the get-go how many hours a day for this and that and every tiny little thing, you'll go insane.
Too many things come up, especially in a big firm, that don't fit into a nice little schedule.
Sure, you may plan to spend only 30 minutes a day eating lunch, but what happens when a partner decides to take you out for an hour and a half lunch. I work for a law firm now, I see partners do this with first-year associates.. i know it happens.
These things are a waste of time.
