The one thing you need to be aware of is that the dissertation is a required step in your research. This is something you need to keep in mind, and it is key to you getting on the right track.
You want to get this out of the way as soon as possible because you know you will not be able to move on if you are not. Your dissertation is the benchmark for your dissertation. You should take pride in it. You should not take the credit out of your history with this. Your dissertation should be the next step of your research.
