Aww Santa, they don't give you a break up there, do they?! Well, I have learned that even in the busiest of schedules we should always find a little time for ourselves: during lunch go for a walk with a co-worker (around a place where you can really have a breather). Try to do some kind of activity after work. Talk to your friends as much as possible. Try to get away at the weekend, if you can. I have a lot of work at the moment but just going for a run in the park in the late evening, reading a book in the subway and being in touch with my friends and family makes me appreciate every second that goes by. That's just me, though. Everyone is different but should always try to find a balance in life:o)
