I had a headache on Friday evening and didn't feel inclined to do homework.
Instead, I watched videos and folded 40 cranes, finishing shortly after midnight. I threaded them and hung them on Saturday morning before starting in on homework.
Speaking of which, I'm currently working on my Masters in Math. I'm taking six graduate level credits while working 30 hours per week, which doesn't leave time for much else. I look forward to folding cranes as it means I'm taking the time to relax.
