I would expand this to say that, in general, to remain well during dedicated study, you will need to schedule in half or full days off. It’s also a good idea to be clear about stop times each evening. You will be more productive and efficient if you know that you are working until 8pm, and then having dinner with a friend, than if you know that you have all evening and plan to study indefinitely. No stop times make it really hard to focus, both because you’re exhausted and because there is no deadline you are working towards (think about how long it takes you to write a paper when you have all week to work on it versus half a day to work on it). Expecting yourself to be focused and productive for more than 12h a day is not a recipe for success.
