The IT sector can be seen as a very challenging, enjoyable but demanding career. Sometimes people want to change career paths and consider a career outside IT. If I wasn't working in IT/academia I would like to work in forestry/renewables.
If however you are not sure what you should be doing then a book by Janice Weinberg Titled Debugging Your Information Technology Career, Elegant Fix Press, 2008 maybe the answer.
Eweek have a good article on this decision making process and some practical career paths.
