i was just thinking about that yesterday. personally, i'll go into industry, work for two years, get no.1, work for another 2 get no. 2 and then i'll be back. the point is, it depends on how you view your job, is it a means to an end or an end in itself. for me, it's a means to an end - the end being a happy family. so am not gonna let some career stop me.
