One of the reasons there is force-field-like resistance to not just doing but really tackling work is that our gear doesn't feel right. By gear, we're talking here about your I/O configuration.
How do you take things in best? Read? Watch? Listen? Different for different subjects? Some of each in a particular order? Where are your challenges? How can you use your strengths to support yourself?
What's the best way for you to get your ideas and notes processed and edited? Nothing like pencil and paper? Gotta have OCR on the iPad to handwrite but get rid of all paper? Easy to speak it out, really hard to write it down?
These are just some beginning questions. Really, you don't stop asking them, because, as you need to get to know yourself and your options better, you start to be able to quickly and effectively strategize about the right sensory mix for the particular task at hand.
True story: I annotate literature with deep thematic reflections that would exhaust me if done by hand. Using voice input and a mobile device, I can make quick work of annotations, capture everything at the speed of speech, minimize the loss of continuity with the reading itself, and enjoy a reduced sense of resistance to doing the work. It's not so bad; I can do this.
Stack this into the volume of similar work a student confronts over the course of their careers. Streamlining your I/O (or not) has a massive impact on your time spent.
Because you talked them out but didn't write them down, do you feel like you've missed some "encoding" of the information? Perhaps. When you go back to these raw, voice-inputted notes to shorten and clean them up, that's where the editing/writing engagement is most needed. Now your "encoding" is happening at the same time you are "integrating" knowledge; when it's not your first pass and you encode more briefly, you also create a more concise and to-the-point study guide for later reference and review.
You'll find the mix. Then change it. Each project will lead you to the efficiency if you know yourself. Now, what looked like way too much extra work has become the path of least resistance. Flow. Like any athlete or artist.
Go get it.
