Not too long ago the (apparently still English) current chair of the doctoral committee informed me that "now all that's left to do is to write and defend a thesis." That seems to have sparked a little bit of a dark mood in me. Now comes the part where you fall deep into a rabbit hole, for years and years on end, and never emerge, possibly not ever again, to see the broad sweep of the plains and the distant majesty of the mountains, is what some part of me seems to have heard.
But that was not what was said, and that is not what you should do. You should remember the way down the rabbit hole, the better to climb up back out of it. You should take note all of the tunnels that go between the rabbit holes, and the intricate networks that they form, and how they transverse the broad sweep of the plain and take you, sight unseen, towards the mountains. You should never forget, as you seem dimly aware of now, that the rabbit holes, for all of their fascinating depths, are only ever part of the story, and that you should never lose sight of the whole.
It will be a constant struggle to remember this, to remain as broad as you could be even as you delve deep into your chosen rabbit hole. But it's something that you can at least try to do, that you must at least try to do---and your work and life will be the richer for it.
