What is a dissertation? It’s a big research paper that is written for several years for the sake of receiving a scientific degree. In a wider sense, it’s a thing that shows your ability to explore a topic, get deep into it, find something new in it, and, finally, put this all together into one paper.
Well, if you need to compose a project in finance, it means that you know exactly the area of your future research and, probably, its topic. Having all this, you need to compose a paper that will represent the way you see your future project. You cannot predict how everything will unfold in the process of further researching. Still, you can produce some scientific prognosis that will be reflected in your proposal.
As you work on your project you should have goals in place to motivate you to finish in a timely manner. As you complete parts of your work you are getting closer to finishing your work according to your schedule. Maybe you can entice yourself to finish sooner if something was waiting for you upon completion. Make it something fun and enjoyable. It helps if it is something you may not usually enjoy. Make things interesting to encourage yourself to finish faster. You can at least consider trying to get your work done a week or so before your deadline.
