Your advisor should help you decide on deadlines for certain parts of your dissertation. It will be your job to stick to these deadlines so you can make steady progress. You will want to construct your own daily schedule for dissertation writing. Do your writing during the part of the day when you are most energetic and your mind feels most active. During other parts of the day, you should schedule time for research, revision and rewriting and also for any jobs or teaching you are doing.
Not only will your advisor be able to help you set realistic goals and deadlines, but he will also help you follow your university's dissertation requirements. Your advisor should give feedback on your writing and help you think through difficult ideas so you can do your best work. Remember, your advisor has gone through the dissertation writing process already, so his feedback can be helpful.
Revision is arguably one of the most important parts of writing. You can revise each dissertation chapter as you write or save all of your revision and editing until after you have a complete draft. When revising, make sure all of your facts are correct, proofread for grammatical and spelling errors and revisit the structure of your dissertation to make sure your sections are ordered in a way that best serves your work.
Writing a dissertation is a huge undertaking with a great investment of time. While you are writing your dissertation, you should make the writing a top priority. This means you should plan your budget ahead of time so you don't run into a monetary crisis midway. Many universities offer financial support for the dissertation year through scholarships, grants and teaching assistantships. Your financial aid office will also have information on outside scholarships for graduate students and those writing dissertations.
