How do you find the time?

As a teacher and Head of a busy English Department, how do you find time to mark?

I must admit, at first the task of marking seemed daunting.  How would I balance marking with my teaching and administration as Head of Department?  I also have a young child who keeps be on my toes.  However, I was pleasantly surprised.  I found that if I planned the marking in stages I could complete it within the required timescales.  I set aside times for each stage - a bit like a revision timetable - and was strict with myself about keeping to those times.
