There’s no secret path that takes you to the end of the PhD.
There’s no list of amazing tips that dodges all of the work involved.
You can’t hack your way past the necessary steps that got your thesis finished.
And that’s good.
All of the work you put into the PhD makes you amazingly qualified for your viva. There’s no way of doing the PhD without putting the hours in. All of those hours help you when you sit down to talk with your examiners.
