Time management

I heard a lot of people say that time management is the most important thing in a B school and being in one, I thought I should perhaps try figuring this one out in more detail. Lets start with the specifics and list down how a student should go about allocating his/her time in a day.

1. Case prep- This would take 6 hours for a 3 case day and 4 hours for a 2 case day (as recommended). Lets assume on average 5 hours per day

2. Classes- 5 hours per day

3. Sleep- as this is important in order to stay human and not become a zombie- lets say 5 hours per day

4. Learning team (study group)- 1 hour per day

5. Gym – 1 hour per day

6. club activities- Assuming an average of 5 clubs per student and one weekday per club- 1.5 hour per day

7. Recruiting activities- includes industry weeks, resume tips, networking with recruiters etc- 7-10 hours per week or roughly around 1.5 hours per day

8 Guest lectures/speaker series – 1 hour per day

9 Power nap in the afternoon- 0.75 hours per day

10. Section events (drinks/parties/movie nights etc)- 2 hours per day

If you add up all the times , it comes to around 25 hours and in this I have not included time for personal hygiene, phone conversations/ skype/ laundry etc.

Every time I think that I have not managed my time well, I find myself revisiting the list above and wondering where the hell should I save time. Should i not spend as much time on the cases ? or should i sleep for fewer than 5 hours? or should i stop going out for section events?

After a month at HBS, I am still wondering.
