As you are planning your summer work schedule, build in some days of rest and relaxation at the beginning, again in a few weeks, and repeat until the end of summer. It’s important to structure in regular breaks and time off. If you have a family vacation planned, build that into your working schedule. Mark out a few days before and a few days after for light work or revision- this will allow you to make dissertation progress while preparing for your vacation. Remember, vacations and rest are important. Build them in early, and take them when they come.
