3.8 When the Going Gets Tough, the Tough Keep Going
"Most things in life that are worthwhile, you gotta work at! You get out what you put in. As simple as that. That's a kind of universal law."
- James Hetfield
Once you have settled for a supervisor and topic, stick with it! At some point, every project worthwhile pursuing gets difficult.
You may need to refine, rephrase, redirect, or narrow your topic but quitting is generally not an option.
The difference between a paper that is good enough and one that is really good is usually decided in the middle of the job, when it takes a lot of perseverance to continue with a thorough analysis of sources and, if necessary, yet another revision of the original plans. This may involve accepting and reacting to critical feedback by the advisor, feedback you may not like, feedback you may not agree with, feedback which may require significant additional work and upset your time schedule.
YOU are the only person who decides whether your paper will be merely good enough or whether it will be a really great paper!
Only in rare cases of serious disagreement about the method and/or results of your research, it may be necessary to change the supervisor at an advanced stage of the work. Do so only if you feel strongly that your work will not be fairly evaluated by the current supervisor.
