I find it weird that so many young people get burnt out, in relatively simple jobs with no responsibilities (on the job or with kids/family).
A couple of people at my office have had to take a couple months of sick leave because burnout. And they had simple responsibilities and no overtime etc.
I myself have worked normal "IT days" for over 15 years, sometimes it's hectic and sometimes calmer. You only have to know how to relax in your spare time. And yes I work at home also sometimes ("bring my work home") and sometimes think about work problems semi-constantly. But going for a run etc helps to clear your head. Or having a robust night out with a killer hangover!
I think these young people just don't know how to work hard and party hard :) And they are crybabies, also.
