You can write a dissertation on any topic. As long as you can defend your thesis and make people care about what you are writing about, then you can be sure that you are in the right direction. The best guides to use when writing dissertations are as follows.
Have a Proposal
A proposal is what will be used to persuade the committee members who will be looking at your thesis on whether your topic is worth pursuing. It is basically a summary of what your thesis is about, how you plan to execute the research and other details.
What makes a dissertation/proposal stand out is the amount of research that has been put into it. That is why you need to read both online and off the net before you start writing. You also need to check out other research studies that have been done around the topic you have chosen so that you can use them to back up your study.
Dedicate Time to Write
No matter how good your thesis/dissertation topic is, if you do not dedicate time to write it, you will fail. Your writing should be coherent, and you should have a flow in the way your thoughts and ideas are being executed. The person who is reading should be able to follow through your thought process without struggling.
Think About Proofreading/ Editing
Even if you think you are a good writer, you should always proofread and edit your work before you submit it. You can also involve or hire someone to help you with the proofreading and editing so that you are sure that the copy you are submitting is clean and that you have not missed anything. The proofreading process is also the one that checks for plagiarism and gives assurance that your work is original.
