My wife struggled quite a bit with my first semester. To outward appearances, it looks like I'm not doing much. I spend hours on end in one spot with a book or a laptop. I don't LOOK like I'm doing anything. So when the chores dropped off substantially she got pissed. For months beforehand I explained that once school started, I wasn't going to be able to spend the time on things like I did before. Then it happened just like I said it would. We had a huge fight about me "not doing anything". It took her a while to figure out that the time I was spending was important, and not "wasted" time. I have to spend hours and hours reading, researching, and writing. That's my full-time job now. The fact I do that job by sitting still in one place doesn't mean I'm not working my *** off. Your brain uses 25% of your resting metabolic rate; when you're actively using it, that can be quite a bit more. It is perfectly possible to be physically exhausted from spending your whole day in your head.
That said, while it dominates your life it isn't the only thing. There is still room for friends and family. Not as much and maybe not in the same ways, but there is some time in each day to devote to the people that matter to you.
Time management is crucial. I'm a pathological procrastinator. I'm awful at managing my time. I started making a To-Do list in Sloth and setting times for each item. I can look at that as "I only have 30min to accomplish this task," or as "I'm setting aside one hour to dedicate to this project." Either way, setting a timer and sticking to it made a tremendous difference. I have time for class, clinicals, work, gym, and family. I have time because I make time. It is NOT easy to make that time, but it's important so I make it a priority. It's up to him to decide where his priorities are and how to manage those.
