Think of the big picture
It is important to think of the big picture. Also, you should take your future into your own hands. Avoid letting other factors such as difficulties or excuses interfere with the progress you are making in your dissertation. For instance, you may have problems meeting your supervisor or the lack of time to meet the chairman of your department regarding your dissertation. However, you should not take it as an impediment in your progress and do your best to follow up with him. Do your best to stick to your word.
Get ready to postpone some things
The moment you begin writing your dissertation, you should realise that you would require time every day for writing, revising, editing, and organising your thoughts. You must remember that once you begin writing your dissertation, there won’t be time for anything else. Decide beforehand as to whether you are really willing to write your dissertation fully or not. You would need to drop any other commitments willingly and be ready to work on your dissertation. The other commitments and activities can always wait. It is just a small price to pay if you want to complete your dissertation successfully and on time. You would need to give up on your television time, your leisure time, etc. for some time and give your dissertation your hundred percent, failing which you would not be able to see the results you desire.
