Studying is the kind of thing I look forward to doing all the time at night once I'm on this solid. That way I can enjoy my days and the outdoors plenty. But for now, it's tough.
I feel like I'm usually mentally between 85-90% during the day and less during the night. To study, especially boring stuff you're not interested in, you really have to be in the 95-100% range.
I'm writing a paper right now, and it's normally much easier to write than this. Same with the studying I did for a test I took Monday morning. But it is possible, so that makes me happy.
