Isaac Asimov: “Writing, to me, is simply thinking through my fingers.”
I found this in one of those quote lists that are everywhere. I like lists, but I love the gems buried in them, and this is a gem. Asimov’s insight is especially profound when it comes to the thesis. It takes a long time to write a thesis. When you sit down to write you don’t have to get it right first time. Sitting to write can help you clarify what you think. Getting something, anything, typed up can help you make the vague clear. It takes time, but when you’re finished and you submit, you’re telling your examiners that you think you’re on to a winner.
If you’ve submitted already, then this is the message you were sending. If you’ve not submitted yet, I think the opportunity here is asking yourself, “What would a winning thesis look like?” Aim yourself at the answer and do the work. Get thinking through your fingers.
